5311,"io_service::post/dispatch, io_service::stop, deadline_timer crashes",nfries88@…,chris_kohlhoff,"I've used programs using boost::asio before, but never used it directly myself. I made a test program using boost::asio that models communications from a synchronous TCP server to an asynchronous TCP client.

<Long version>
The program launches one thread for the server, which creates an acceptor and calls async_accept; then runs the io_service. Upon accepting a new connection with success, it immediately begins an async read on the new connection and another async_accept.
On the original thread, I create a TCP socket (using a separate io_service), connect it to the server, and send a packet saying ""Hello, Server"".
When the server thread receives this ""Hello, Server"" packet, it responds with a ""Hello, Client"" packet and begins another async_read with a newly-allocated buffer.
When the client receives this ""Hello, Client"" packet, since the test program has nothing else to do, I begin cleaning up by calling io_service::stop on the server's io_service.
That crashed. I guessed that maybe it was my fault, so instead I called service.post(bind(&io_service::stop, &service));. This crashed, so I tried the same with service.dispatch(). Now I was confused, so I tried a third time with a deadline_timer that expired after 1 millisecond. This also crashes.

<Short version>
io_service::post, io_service::dispatch, and io_service::stop are all crashing when called from a thread other than the one running the io_service. An async_read and async_accept are in progress, but no reading or connecting is being done.
deadline_timer::async_wait() crashes when called from a thread other than the one calling io_service::run

Also, none of these crashes are caught by try{}catch(){}.
