Hi, I have written the thread support for a customer of us. I wrote and tested it for Perl 5.8.0. I guess some of the internals of the Thread Handling in 5.8.2 have changed and makes things incompatible.
Do you have any chance to test the same scripts with Perl 5.8.0 ? Can you provide we a stack backtrace from the segfault? I am vey low on time at the moment, but I can see if I have a quick idea how to solve the problem.
