Answer by ApproachingDarknessFish for Generate the longest error message in C++

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 used by the compiler. And it's showing no signs of stopping.

EDIT:

One hour later, now at 36,000 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: 38,876 compiler errors, 544,624 lines of error messages, totaling 48.8 megabytes of data, and 518.9 megabytes of RAM used by the compiler before it crashed.
