Same goes for the >> SigC testsuite. So I must suspect a bug in cygwin, libstdc++6, or both. Do you have a STC using just qmake itself so that I only have to build a single package to try and track this down? e.g. does it fault just on startup, can I just run "qmake --help" and reproduce the problem? 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
