working for me. The limit syntax can be tricky across shells.
bash-2.05a$ ./a.out
Segmentation fault
bash-2.05a$ ulimit -c unlimited
bash-2.05a$ ./a.out
Segmentation fault (core dumped)
Or if you're in the C shell:
% ./a.out
Segmentation fault
% limit coredumpsize unlimited
% ./a.out
Segmentation fault (core dumped)
The core files get deposited in /cores.
You can also change the resource limits in code in case you don't want
your user to grovel around in the shell if you want to get a core dump.
See the tail end of my gdb overview at
http://macedition.com/bolts/bolts_20030210.php for the code (which may
also have been posted on one of the cooca lists before)
