Write a short program, that would generate the longest possible error message, in a standard C++ compiler (gcc, cl.exe, icc, or clang).

The score of each entry is the number of characters in the longest error message the compiler emitted. Types included in your source code and quoted by the compiler are counted as a single character.

Cheating

You can always redefine a template in template in template with long names, but I expect something creative. I tried to prevent some of that by the last rule, but of course the rules can be better, and I'll be glad for improvements.

Edited the tags. I admit that [kolmogorov-complexity] is a bit of a stretch, but I think it is expressive in this case. –  dmckee Apr 4 '11 at 22:04

Maybe you should go for a ratio: Error.message.length / code.length. –  user unknown Jun 30 '11 at 16:28

Template error messages are fun to decipher. Consider this:

#include <vector>
#include <algorithm>
int main()
{
    int a;
    std::vector< std::vector <int> > v;
    std::vector< std::vector <int> >::const_iterator it = std::find( v.begin(), v.end(), a );
}

Compiling with gcc -c error.cpp (4.6.3) will produce 15786 bytes of output, with a longest line of 330 characters.

Hm. What about #include __FILE__ and a very long filename..? –  AKX Jul 1 '11 at 16:22
    
@AKX Right. Thanks. Reduced by 4 characters :) –  BЈовић Jul 1 '11 at 16:33
    
Why does this do that? I'm curious now. –  Rob Jan 17 '13 at 17:38

@Rob it includes the same file over and over, and it redefines main every time. –  BЈовић Jan 17 '13 at 17:41

98 (necessary) characters:

template<class T>struct W{T v;W(T v):v(v){}};
template<class T>int f(T x){f(W<T>(x));}
main(){f(0);}

Ungolfed (produces longer output):

    T value;
    Wrap(T v) : value(v) {}

I discovered this when I wanted to see if C++ supports polymorphic recursion (and, as you can clearly see, it doesn't). Here's a trivial example of polymorphic recursion in Haskell:

Prelude> let f :: (Show a) => a -> String; f x = show x ++ " " ++ f [x]
Prelude> f 0
"0 [0] [[0]] [[[0]]] [[[[0]]]] [[[[[0]]]]] [[[[[[0]]]]]] [[[[[[[0]]]]]]] [[[[[[[[0]] ...

Here, this requires Haskell to act like it instantiates Show x, Show [x], Show [[x]], Show [[[x]]], ad infinitum. Haskell does it by turning (Show x) => into an implicit parameter to the function f added by the compiler, something like this:

type Show a = a -> String

showList :: Show a -> [a] -> String
showList show []     = "[]"
showList show (x:xs) = '[' : show x ++ showItems xs where
    showItems []     = "]"
    showItems (x:xs) = ',' : show x ++ showItems xs

f :: Show a -> a -> String
f show x = show x ++ " " ++ f (showList show) [x]

C++ does it by literally trying to construct such instances until the template instantiation depth is exceeded.

Inflated to 102 bytes (cl doesn't like implicit int in C++ mode) it generates 14.380.923 bytes of error output after 4½ minutes of CPU time and a peak of about 100 MiB of memory usage. –  Joey Apr 5 '11 at 8:51
    
Could you explain what have you tried to achieve with polymorphic recursion? Because in an example both in Haskell, and in C++ the process is infinite, only difference is it occurs in run or compile time. –  sukhmel Jun 25 at 19:17

a G(foo)

With gcc 4.2.1, generates the error error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘foofoo....foofoo’ with 2^21 copies of foo. 6,291,558 bytes in all. It's about as big an identifier as I can get, replacing foo with food generates an ICE.

Read the instructions! You should generate a single long error, not many short errors. –  Elazar Leibovich Apr 5 '11 at 7:47

Based on a message length / code length ratio, this may be the best solution:

Message (77):

code: file not recognized: File truncated
collect2: ld returned 1 exit status

77 / 0 = Inf

+1 Clever way, best ratio! But not longer message... –  Synxis Nov 26 '12 at 19:47

Similar to VJo:
a.cpp:

int main() { return  
#include "a.cpp"  
#include "a.cpp"  
}

g++ a.cpp

produces a lot of output (at least 2 gigabytes before I killed it)

The following code is based on an actual error I once encountered.

template <int i>
void bar();

template <int i>
void foo()
{
    bar<i>();
    char baz[i];
}

template <int i>
void bar()
{
    foo<i-1>();
}


int main(void)
{
    foo<2000>();

    return 0;
}

(using gcc)

Pretty obvious template recursion, but since I used ftemplate-depth=100000 for this run this doesn't produce an error. The real source of the error messages comes from char baz[i];, which produces an error when i drops to -1.

After about half an hour, I'm sitting on 21,000 compiler errors, 300,000 lines of error messages, and 280 megabytes of RAM. And it's showing no signs of stopping.

EDIT:

One hour later, now at 36000 compiler errors, 504,000 lines of error messages, and 480 megabytes of RAM... and still going.

EDIT #2:

About half an hour later:

ccplus1.exe has stopped working

Final statistics: 38876 compiler errors, 544624 lines of error messages, totaling 48.8 megabytes of data, and 518.9 megabytes of RAM.

I'm sure none of those error messages even point to the real issue... which is typical of the average STL typo. –  Mark Lakata Mar 21 at 5:24

C++11 variadic templates (69 characters)

template<int... p>
void f()
{
    return f<0,p...>();
}

int main() {
    f();
}

Configuring maximum template instantation depth you could set the length of the error. Here is an example using GCC 4.8.1 with default template depth (900):

prog.cpp:4:22: error: template instantiation depth exceeds maximum of 900 (use -ftemplate-depth= to increase the maximum) substituting ‘template void f() [with int ...p = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}]’ return f<0,p...>(); ^ prog.cpp:4:22: recursively required from ‘void f() [with int ...p = {0}]’ prog.cpp:4:22: required from ‘void f() [with int ...p = {}]’ prog.cpp:8:4: required from here

I stumbled across this by accident:

#include<functional>
#include<algorithm>
#include<array>
#include<stdexcept>


int main(int argc,char** argv){
    std::array<double, 3> arr;

    arr[0] = 0; arr[1] = 1; arr[2] = 1;

    if (std::any_of(arr.begin(), arr.end(),
                    std::bind(std::less_equal<double>(), std::placeholders::_2, 0))){
        throw std::invalid_argument("Geometry with bin width less or equal to zero");
    }
}

On c++x11 it produces 44kb of error messages, in which compiler tries to say: Please define placeholder for first argument if you define it for second.

See it on ideone.

I'm terrified of making a typo in a C++ program that uses the STL... –  Mark Lakata Mar 21 at 5:27

C++

Based on BЈовић's solution:

File: golf.cpp:

#include "golf.cpp"
#include "golf.cpp"

Running this under G++ will not finish, however, I have computed the length of the error it will eventually emit as roughly 85*2^140 terabytes.
