That's because stdout is already closed by the time your dtor runs. I stepped right into it, it does the printf call but somewhere down in the dll it checks the flags field in the stdout FILE object for read/write and finds it's not open for either, so it's at eof. Grep 'cantwrite' if you really want to find it. Anyway, your dtor is called. 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/
