[Boost-users] bug in asio?

Hi, I am using a 3rd party library that uses boost::asio. The 3rd party library will call asyn_receive() with a callback handler, then when boost::asio::detail:: receive_op::do_complete() calls the callback handler, the handler consumes the message, calls asyn_receive() and then if there is no more message, it (the thread) waits for a condition -- the callback handler gets called again. The problem now is that once there is no more message, the thread enters the wait condition, and it never gets waken up again. Is it incorrect to enter the wait condition in the same thread that calls boost::asio::detail:: receive_op::do_complete()? Thanks in advance. Cheers, Hei
