The cause is failure of setsockopt(). setsockopt() before accept() failed with EALREADY. I looked into fhandler_sock_local.cc. In fhandler_socket_local::af_local_set_no_getpeereid(), connect_state() is checked if it is 'unconnected', however, it is 'listener' after listen() is called. So it failed. -- Takashi Yano <takashi.yano@nifty.ne.jp> -- 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
