Cygwin's g++. The default cygwin terminal. Another bit of data: if I explicitly redirect the output to /dev/tty0, I also get no output. E.g. # outputs "hello" echo hello > /dev/tty0 # no output ./foo > /dev/tty0 -- 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
