I'm afraid you're probably going to have to get into some hardcore debugging of your program and find out _why_ it exits. Are you _sure_ that third SEGV is the same kind as the others, or is it perhaps a real SEGV and you overlooked the differences? Or you could run your program to that third SEGV, then try single-stepping it instead of continuing and see where it goes next and how it gets from there to abort/exit. cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
