34 <PRE> SIGFPE only happens on divide by zero, and in the few places where
35 Services divides by a variable the variable is already tested for being
36 nonzero. SIGQUIT is user-generated. SIGABRT isn't generated at all.
37 SIGILL only occurs if your compiler is broken or you run a binary compiled
38 for the wrong CPU.

45 </I>&gt;<i>Why does DUMPCORE only turn off the SIGSEGV handler? there are other
46 </I>&gt;<i>signals that cause core dumps
47 </I>&gt;<i>(like SIGFPE, SIGQUIT, SIGABRT, SIGILL etc) that we definitely would want
48 </I>&gt;<i>to dump core if we want
49 </I>&gt;<i>SIGSEGV to do so.
