Weird GeneralProtectionFault on win32 when using thread-based-fork

Attached is the minimal test case I could come up with. Note that there is are no moving parts whatsoever - just a connect and a fork, no data changes hands.

I'd guess, at first sight, that the DBI is just the 'canary in the coal mine' here and the underlying issue is in the perl core. I don't use windows, at all, so I can't reproduce it. A detailed stack trace would probably help. Tim.

Is this still a problem with current Perl and DBI versions?

Hi Christian. Do you think you could run the script attached with this ticket on a recent DBI/Perl combo on win32, and see if it still fails? Thank you!

With ActivePerl 5.12.4 it crashes, with Strawberry Perl 5.16 it does not: https://gist.github.com/0942c9e6d5aa3cafaf5a Does that help you guys or do you need more?

I don't have easy access to windows currently. I would assume it is still a problem on earlier perls just like in the original message.

Thanks for the updates. I'm closing this as not a DBI bug. Feel free to reopen if you feel it is a DBI bug and it's worth fixing.
