It seems that a signal can cause pthread_join to incorrectly return EINVAL. I debugged it only a little but hopefully someone finds this useful:
In the file thread.cc, function pthread::join, the call to cygwait may return WAIT_SIGNALED if a signal is sent to the process. The switch statement handling the return value assumes that only WAIT_OBJECT_0 and WAIT_CANCELED are possible. The default section of the switch statement has a comment "should never happen" and it returns EINVAL. It might be that the problem occurs only when SA_RESTART isn't used. -- Lasse Collin | IRC: Larhzu @ IRCnet & Freenode -- 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
