I would like to connect to a TCP server with a timeout. If the timeout expires, I should close the connection as soon as possible as the IP address (chosen by a user) is probably wrong. With my computer, closing the socket takes about 15 seconds to complete, which makes my program not responsive for a while. On Linux the same code seems to be fine. I attach a code that reproduce the problem." Bugs new Boost 1.58.0 asio Boost 1.57.0 Regression boost asio async_connect
