in reply to Debugging tips for segmentation faults?
Further, to hv's comment, I don't get core. I'm running as root. And my code won't work without root privileges. :-) But compiling a debugging perl may be an option. Thanks.
You probably have your ulimits set to not produce a core file. Before testing your script, set your ulimits (assuming bash) with
> ulimit -c unlimited
