What happens is it hangs on that openpty() call. It displays Start immediately. But then around a minute later it shows the rest.
$ ./a.exe Start. ** hangs here about 1 minute ** PTY opened. PTY closed. I took the liberty of adding time() calls just before and after the openpty() call: $ ./a.exe Start. 1580578712 PTY opened. 1580578772 PTY closed. It turns out to be exactly 1 minute -- like there's a 60 second timeout waiting for something... -- 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
