I profiled the code, and found that it was crashing in DB_File::DoTie_. I checked my version (1.72) and then upgraded to the latest on CPAN (1.802).

When I ran the profile again, this time it crashed in one of my DEBUG routines. I ran it again, and it changed to one of my file locking routines. It seems to be jumping all over the place.

So, I jumped to a FreeBSD machine running 5.6.1, checked out the code and re-ran the identical test and it worked without any problems. Besides the 5.6.1, the other machine also has a newer version of Berkeley DB, so I am rebuilding the DB version on my machine to see if that makes a difference.

(Some time passes...) I changed from Berkeley DB 2.4.14 to 2.7.7 (to match one of the production machines), re-ran the script and sure enough, it moved the segmentation violation to yet another place in the code :-(

At this point, I am have to go with the assumption that the problem is caused by Perl 5.6.0
