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^

“¿µƝɓṭỵae»Ȯ:

Try it online!

Explanation:

“¿µƝɓṭỵae»Ȯ:

          Ȯ     Print
“¿µƝɓṭỵae       A string...
         »      Decoded from base-250
           :    Integer division

As the integer division is a dyad, it will implicitly take the chain's current value as both arguments - which is a string. Crashes because it expects integers.

sed, 32 bytes

iGoodbye Cruel World!
w/dev/full

i inserts a line, and w writes to a file. /dev/full in this case because all writes to it return ENOSPC ("No space left on device").

It still needs a single line of input to work, though.

$ echo 1 | sed -f crash.sed
Goodbye, cruel world!

"!dlroW leurC eybdooG">o<

Basically it adds the string to the stack (Backwards, last in first out) and then does the equivalent of:

while(1):
  pop the stack
  print the character

When there are no characters left on the stack (The whole string has been printed) popping the stack gives an error

SOGL, 15 25 17 bytes / 2 = 8.5!

Q7┌θ/²?‘■←#c℮‘o0n

Explanation:

...‘           push "goodbye cruel world!"
    ...‘       push "hello world!"
         o     output "Hello World!"
           0n  attempt to make an array where each line is 0 characters long, making the array
               required to be infinite, which crashes (OutOfMemoryError)

(Ab)uses the fact that SOGL uses STDERR as a debug output, so in it there is a lot of text, along with the line

`∑`@22: ["goodbye cruel world!"]

If you piped the STDOUT of the Processing sketch to a file, the "Goodbye Cruel World!" would be there.

APL (Dyalog), 17.5 bytes

Without bonus, 20 bytes

Goodbye Cruel World!

Try it online!

Note that the code is unquoted, so APL tries to execute it but World is not defined, causing a VALUE ERROR crash with the offending line of code included in the error message.

With bonus, 35 ÷ 2 = 17.5 bytes

'Hello World!'
Goodbye Cruel World!

Try it online!

First prints the required string, then crashes like the above program.

More sofisticated bonus version, 35 ÷ 2 = 17.5 bytes

⍎'Goodbye Cruel',5↓⎕←'Hello World!'

Try it online!

Prints the first string, then drops the first five characters from that (5↓), then concatenates that (,) to a new prefix, and then attempts to execute (⍎) that, causing the same error as above.

TeX, 19!

Hello World!#\bye Goodbye Cruel World!

To force TeX to actually produce a dvi/pdf file without manual intervention, compile with -interaction=nonstopmode.

It prints Hello World!, throws an error for using # when you're not supposed to and then stops compilation with \bye. However, whatever's after \bye is still output in the error message, so it applies for the bonus.

Answer 17

WinDBG (Windows XP/Vista Local Kernel Debugging), 33 bytes

.echo Goodbye Cruel World!;.crash

Warning: This will crash the entire machine, not just the program.

Local kernel debugging is only allowed on Windows XP and Vista (but not enabled by default in Vista). The WinDBG dialog on local kernel debugging does't mention any other Windows OS so I assume it can't even be enabled for those. Presumably for other Windows OS's you can attach to a remote machine for kernel debugging, but it's the remote machine that will crash so I don't think this solution counts there.

Bash 20.5! 18.5!

I am not going to bash jelly, but I am a little bashful of my bash at bashing out a quick bash script. 18.5 isn't too bad for a non-golfing language. (Note this has to be a script, interactive bash will try to interpret ! as a history lookup)

echo Hello World!
Goodbye\ Cruel\ $_

Returns with error code 127 and:

As requested no "'s... anywhere :). As suggested by apricot boy I now lookup the last argument of the previous command to save 4 bytes.

Jelly, 10.5! bytes

“,ḷṅḳȦ»¹“¿µƝɓṭỵae»+/R

Try it online!

This exploits undefined behavior, using Python strings (strings) instead of Jelly strings (list of 1-char strings). The conversion is done by reducing the Jelly string by addition, and Python's + concatenates two strings, so two strings added together are concatenated Python-wise. Then, it uses the appropriate monad (range) so that Python's int is called on the string, resulting in an error that would always contain Goodbye Cruel World!.

Explanation:

x86-64 Binary Code (with Linux system calls), 43 bytes

Disassembly:

0:  31 c0                   xor    eax,eax
2:  ff c0                   inc    eax            ; write syscall number = 1

6:  ff c7                   inc    edi            ; stdout file descriptor = 1

Note: 0x16 code bytes + 0x15 string bytes = 0x2B = 43 total bytes

This program bundles the data it needs (the string "Goodbye Cruel World!\n") into its own code. It loads a pointer to that string using rip relative addressing, and calls the write syscall directly rather than through a glibc wrapper, so it's entirely position-independent, and we can easily test it by embedding the code into a const string and casting that string to a function pointer. To crash the program, I end it with a hlt instruction, which with ring 0 privileges would silence the processor forever (or at least until the next interrupt comes in), but with ring 3 privileges (typical for user programs) we get a far less dramatic Segmentation Fault.

Test Program:

#include <stdio.h>

const char code[43] = "\x31\xC0\xFF\xC0\x31\xFF\xFF\xC7\x48\x8D\x35\x07\x00\x00\x00\x31\xD2\xB2\x15\x0F\x05\xF4Goodbye Cruel World!\n";

int main() {
    printf("Code bytes: %zi\nNow running the code:\n\n", sizeof(code));
    ((void(*)())code)();
    printf("Failed to crash, now exiting!\n");
    return 0;
}

Output:

Code bytes: 43
Now running the code:

Goodbye Cruel World!
Segmentation fault

Note that the 43 byte code is a complete program as specified by the challenge, not just a function. It doesn't depend on the main function of the test program to function correctly; it would still print the string and crash if loaded and jumped-to by the loader directly.

Prints Hello World! to stdout and Goodbye Cruel World! to stderr. Crashing is easy in machine language. To Try it online!, compile and run the following C program.

const char main[]="\xe8 \0\0\0Hello World!Goodbye Cruel World!Yj\1[j\fZj\4X\xcd\x80\1\xc1\xb3\2\xb2\24,\b\xcd\x80n";
