How to get core from SEGV?

[Albert Chin <gnome-devel-list mlists thewrittenword com>]

We've built gpdf-2.10.0 on Solaris 10 but it's dieing on startup. We'd
like to examine the core file but none is generated. We're rerun with
GNOME_DISABLE_CRASH_DIALOG=1 but that didn't work. We then removed the
SIGSEGV handler from GConf but still cannot get a core file to debug.
How do we get a core?
