This looks like almost certainly a simple perl bug. Threads was Jerry Heddens working arena lately, but there are complicated things going in core. If it's easily reproducible best would be to start with a debugging perl and break at the point which tries to read from 0x4. BTW: I thought about adding -debug packages in general (to cygport) as with fedora, but got distracted somewhere. -- Reini Urban -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
