On my Fedora Core 2 system, SIGABRT and SIGSEGV both cause a process
to dump core, but by default the system is configured to prohibit
coredumps (ulimit -c 0).  If I increase these limits before starting
the process I want to get a coredump from (ulimit -c 10000000) I get
the dumps fine.  This assumes the process you want to get a dump from
isn't intercepting SIGABRT or SIGSEGV.

If you can't set the limits beforehand, you might be able to attach
with gdb, use setrlimit to eliminate the coredump restriction, then
send an ABRT or SEGV signal.
