Thanks for this. I got a similar explosion on Win32 using fork (pseudo-fork) and fixed it as you suggest by switching to Storable::dclone. The bug could be replicated, but depended strangely on input data and other interactions. It also required lots of work to get an error message. Initially it crashed with a Windows crash dialog and nothing on STDERR. Nasty bug.

The error, for the sake of frustrated searchers is: 

Attempt to free non-existent shared string '°ÿ2♦', 
Perl interpreter: 0x4377f9c at C:/Perl/site/lib/Class/DBI.pm line 1032
