[ ... ] Sounds like libsigsegv knows what it's doing and is only doing what it should and correctly leaving to Cygwin things best left to Cygwin. (Plus a quick browse of the source made reinforced that impression; it doesn't replace but carefully chains in front of the cygwin exception handler and passes through any exceptions it doesn't eat.) cheers, DaveK -- 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
