There are basically two reasons why your program segfaults (at least I can think of two).

The first is a bug in perl. You can try to run your script with perl-5.10.0 or perl-5.8-maint (the soon-to-be 5.8.9). Both contain many fixes for bugs in perl-5.8.

The second possible is a non-thread-safe XS module that you use, or a buggy XS module. Without knowing what modules you use this is impossible to diagnose remotely.
