Throwing exceptions from a signal handler is a can of worms that requires support from both the compiler and the C runtime. I was working on adding this support for the distro package of gcc-4.5 before I had to go AWOL a couple of weeks ago; it requires building the Cygwin DLL with EH tables, and adding support in the last-chance stack unwinder in libgcc that is able to unwind past our sigfe/sigbe stuff. I'll be back in the Cygwin/GCC world starting next week. 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
