Greetings,

I am very strange for that! I work on Solaris 2.7, C language program,
compiled by gcc. Sometime, I find core file. With gdb open the core file, it
shows that terminated by signal 9.

My confusions are:

1) How signal 9 can generate core file? Normally signal 9 will terminate
process immediately and directly, no core file generated.

2) Basically, we are sure no people kill the process with signal 9. Could
system kill the process automatically under some condition?

Thanks in advance!
Evan

I have some code that does the following:

void
sig_handler(int s)
{
    fprintf(stderr, "%s\n", signalstr(s));
    if (s == SIGSEGV || s == SIGINT) {
        raise(SIGKILL);
    }
    sleep(1);
}

If your program is faulting miserably you might as well deliver the Coup
de Gras.

"Bug in gdb".
