This is something I wanted to bring to the dev mailing list.
I wanted to prepare at least three tests, if possible four:
- one thread (if possible two variations: signal to one particular thread +
signal to all threads)
- multiple threads (signal to one particular thread + signal to all threads)
And this in combination of all supported targets (x86_64, i386, etc).
Emitting SIGABRT for such program gives core of size 97kilobytes:
int main(){for(;;);}
I will write assembly programs for the above cases, without libc.
