--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Now what collect2 does:
#ifdef SIGQUIT
if (signal (SIGQUIT, SIG_IGN) != SIG_IGN)
signal (SIGQUIT, handler);
#endif
if (signal (SIGINT, SIG_IGN) != SIG_IGN)
signal (SIGINT, handler);
#ifdef SIGALRM
if (signal (SIGALRM, SIG_IGN) != SIG_IGN)
signal (SIGALRM, handler);
#endif
#ifdef SIGHUP
if (signal (SIGHUP, SIG_IGN) != SIG_IGN)
signal (SIGHUP, handler);
#endif
if (signal (SIGSEGV, SIG_IGN) != SIG_IGN)
signal (SIGSEGV, handler);
#ifdef SIGBUS
if (signal (SIGBUS, SIG_IGN) != SIG_IGN)
signal (SIGBUS, handler);
#endif
I guess SIGQUIT and SIGSEGV and SIGBUS should be added too.
Also collect2.c should move over to fatal_signal instead of its own handler too
