Goodbye Cruel World!

Question

Background

Hello golfers! I would like to learn all the programming languages! But I kinda have a short attention span... and copying all the Hello World examples gets boring... but I like fire! ^w^

Challenge

So here is the plan! I want you all to write the smallest code that will compile, print Goodbye Cruel World!, and then crash. Or, as a bonus twist challenge, print Hello World! and crash with Goodbye Cruel World!

Rules

Your score will be total character count used. The answer must be a whole executable program.
Your program must print Goodbye Cruel World! to output, and then crash (unexpected error).
- For a score bonus, you must print Hello World! to output instead, but the error message must also contain Goodbye Cruel World!. If you complete the bonus challenge, you may divide your score by 2. (Include a ! at the end of your score if you are claiming the bonus!)
As long as the standard output still prints, and standard error still prints, the order doesn't matter. Just as long as neither can block the other from happening.
The output must contain the contents of the above; " shouldn't appear in the output.
The output should contain the specified string, and nothing else.
The crash report can contain anything, but to claim the bonus, the following regex should match /Goodbye Cruel World!/mi (aka, contains, ignore case/surrounding text))
The strings Hello World! and Goodbye Cruel World! are case insensitive, but otherwise should appear exactly as above.
If the language is capable of crashing (it cannot change its exit code), it needs to crash. Otherwise use the standard "error report" (i.e., STDERR) for the language.

I can crash Python 3, so I have included an example Python 3 answer! Now lets all set the world on fire! ^W^

as a bonus twist challenge, print "Hello World!" and crash with "Goodbye Cruel World!"? — Magic Octopus Urn, Jun 8, 2017 at 14:34
@Riker Did you mean to say "is not code-golf"? I think it still is, as the bonus is just an optional, harder version. The bonus modifier is just to make it viable as the preferred solution. My other options are post as separate question (would be closed as a dup), or use a different tag (which, at the end of the day, this is just 2 different difficulty code-golf challenges together, so doing that would defeat the point of the code-golf tag). For any rule, there will always be a good exception (I think this use case counts as one) And no one here seems bothered by it. — Tezra, Jun 16, 2017 at 15:47

x86-16 machine code, PC DOS, 28 bytes

00000010: 7275 656c 2057 6f72 6c64 2124            ruel World!$

Unassembled listing:

B4 09       MOV  AH, 9              ; DOS display string function
BA 0107     MOV  DX, OFFSET BYE     ; load address of message
CD 21       INT  21H                ; print and say goodbye
       BYE  DB  'Goodbye Cruel World!$'

Explanation

This will first display the string below without terminating the program. It will then continue to execute the subsequent memory contents as random CPU instructions, including jumps to other code, hardware, etc.

This will likely crash DOS to the point that a hard reset (power cycle) of your PC will be required.

Octave, 28 bytes

disp"Goodbye Cruel World!"
d

Try it online!

This displays "Goodbye Cruel World!" in the shortest possible way in Octave (by skipping the parentheses and avoiding a space).

The d on the next line is an undefinied variable, so it errors with the message:

error: 'd' undefined near line 2 column 1
error: called from
    .code.tio at line 2 column 1

If it's OK to output: ans = Goodbye Cruel World! then it can be 24 bytes.

Go, 76 bytes, score 38!

package main
func main(){print("Hello World!");panic("Goodbye Cruel World!")}

(Edit: switch strings around).

Formatted:

package main

func main() {
        print("Hello World!")
        panic("Goodbye Cruel World!")
}

No semicolon in formatted version because of the line breaks.

Might be able to reduce this with a wizardry int-->string hack, but whatever.

Ruby, 43 42 bytes/2 = 21!

puts"Hello World!"
-"Goodbye cruel World!"

Saved half a byte with the help of Alexis Andersen, by replacing "String"/0 with -"String". This only "works" with Ruby versions lower than 2.3, in which the unary minus method was actually added to the String class!

With Ruby < 2.3:

$ ruby -e 'puts"Hello World!";-"Goodbye cruel World!"'
Hello World!
-e:1:in `<main>': undefined method `-@' for "Goodbye cruel World!":String (NoMethodError)

With Ruby >= 2.3:

$ ruby -e 'puts"Hello World!";"Goodbye cruel World!"/0'
hello world!
-e:1:in `<main>': undefined method `/' for "Goodbye cruel World!":String (NoMethodError)

It prints Hello World!, then try to evaluate Goodbye Cruel World!. It fails doing it, because that string is not a valid code.

Alice, 44 40 bytes, score 22 20!

"!dlroW olleH"d&o`Goodbye Cruel World!é

Try it online!

-4 bytes by finding an interpreter bug.

Explanation

"!dlroW olleH"       push this string (one character at a time)
              d      stack depth
               &o    output that many bytes
                 `   print debug information

The Alice interpreter is written in Ruby, which can be strict about character encoding. When the debug command attempts to output the é (or any character in the range 0x80-0xFF) at the end of the program, this character is interpreted as ASCII-8BIT instead of UTF8, causing a crash.

SmileBASIC, 44/2 = 22 bytes!

At first I thought there would be no way to get the bonus, since errors in SB only show a specific message along with the line number (ex: IF without THEN in 0:4) But then I remembered that MML (the language used for playing music) gives more detailed error messages, which display the code that caused the error!

?"Hello, World!
BGMPLAY"Goodbye Cruel World!

Output:

Hello, World!
Illegal MML in 0:2(BGMPLAY:1)
  Goodbye Cruel World!
    ^
 Missing number (in Track 0)

The error occurs because the o (set octave) command expects a number.

Assembly (MIPS, SPIM), 97 92 bytes

.data
a: .asciiz "Goodbye Cruel World!"
.text
.globl main
main:
li $2 4
la $4 a
syscall
j $0

Try it online!

Not gonna lie, i haven't touched MIPS in a long time. Plus i'm not familiar with what shortcuts i can use with SPIM, but i'm satisfied.
For those of you not familiar with mips, the dumbed down version: data declares allocated data (obviously) which in our case is the ascii string. Text is our function space, and main is our main method. Interestingly, mips lacks a native output, so we need a system call for this.
li $2 4 means load immediate, or put a number in this register. In this case 4, to the $V0 register. This will tell the system call what it's doing, and 4 roughly means "print text"

la $4 a Next, we load the address of our text into a register so that the system call knows what it's printing.

Then we call syscall our system call.
To break it, i jump to 0 which is essentially a goto. 0 is not a valid target, so it errors. This saves 5 bytes over divide by zero.

Edit: Safe Alternative 112 Bytes.

Try it online!

If you're not fond of a program running until it essentially overflows the stack, this will create an exception and exit safely thereafter. This one does so by trying to read from a misaligned location, which is a few bytes shorter than divide by zero.

Quick note: jump to 0, aside from causing errors, is an incredibly unexpected behavior - what it does is fail spectacularly. Afaik most emulators for mips will just error and call it a day, though i can't vouch for all of them. If this behavior is too much of a "watch the world burn" i can tone it down to whatever is desired, i guess — Andrew Baumher, Aug 21, 2019 at 3:00

F#, 71 bytes

[<EntryPoint>]
let main a=
  printfn"Goodbye Cruel World!"
  a.[0]|>int

Try it online!

The function main takes an array of strings a and has a return value of integer. The program attempts to get index 0 of the arguments, even though there are no arguments. The |>int converts a.[0] to an int, or otherwise, the program wouldn't compile because the return value has to be int. The boilerplate code [<EntryPoint>] kind of made it necessarily long but you, unfortunately, cannot get rid of it.

\$\begingroup\$ I don't now much about F#, but at least the Hello-World Example on TIO runs fine without the [<EntryPoint>] boilerplate, so it might be worth checking out when exactly it is needed. Try it online! \$\endgroup\$

\$\begingroup\$ I just found there is an implicit entry point. Then the whole main is not needed and just printfn"Goodbye Cruel World!";[].[0] would work with the same error: Try it online! \$\endgroup\$

Perl 5, 43/2 = 21.5 bytes!

say'Hello World!';die'Goodbye Cruel World!'

Pretty straightforward. die just crashes the program with the given error message plus some extra fluff.

\$\begingroup\$ Can't remember the exact rule but this program doesn't run without the -E flag, so you need to add at least one byte. \$\endgroup\$

\$\begingroup\$ @pipe The -E flag is allowed on this site without a penalty, since it's arguably the "normal" way of writing a perl one-liner. \$\endgroup\$

\$\begingroup\$ The output should contain the specified string, and nothing else. -- This prints extra quotes around the string. \$\endgroup\$

APL, 28

÷~×⍴⎕←'Goodbye Cruel World!'

This first displays the text, then tries to take the reciprocal ÷ of the not ~ of the sign × (an integer 1) of the length ⍴ of the text. As the sign of the length will always be 1, the not of which is 0, the reciprocal will produce a DOMAIN ERROR.

In all fairness, ngn\apl does not crash, rather will output infinity. Nearly all other (legacy) APLs such as Dyalog, APL2000, and IBM APL2, do not handle NaNs or +/-Inf and will crash as expected.

\$\begingroup\$ You can just remove ~×⍴ since the reciprocal of a string gives a DOMAIN ERROR on all APL systems. \$\endgroup\$

print"Goodbye Cruel World!"z

It just prints "Goodbye Cruel World!" then tries to call unknown function z (so it crashes)

Java 6, 83 bytes, Score 41.5!

Java 6 loaded static initializers before searching for the main method, making it possible to bypass the lengthy main signature. However, past 6, it first looks for the main method and then static initializers, making this solution void.

class A{static{System.out.print("Hello World!");new Long("Goodbye Cruel World!");}}

Expanded:

class A {
    static {
        System.out.print("Hello World!");
        new Long("Goodbye Cruel World!");
    }
}

Goodbye Cruel World!
