A standard fedora install these days does all sorts
of stuff to intercept core files (which is an incredible
pain in the butt when you want to get an actual core file
for debugging).

Check the contents of /proc/sys/kernel/core_pattern
(and other core_* files in that directory)

You can permanently override this by sticking
this line in /etc/sysctl.conf:

kernel.core_pattern = core

Of course there is also the ulimit setting. Regardless of
all the /proc/sys stuff, you won't get a core file
unless you run the program after setting

ulimit -c unlimited
