Attached is a piece of sample code in which I'm trying to use Boost.Asio to dispatch a call that will cause the program to shutdown, however for some reason the io_service is not ever calling the handle_stop method, so the program does not shutdown.

...

 bool run = m_io.poll_one() >= 0;

the return value of poll_one() is always >=0 (it's size_t), so run is always true and the condition if(!run && m_stop) is always false.

sorry that's a typo but actually irrelevant as the handle_stop is still never called.

here is a simpler version with output that shows the same behavior http://ix.io/16b

and here is a fixed version of what was previously attached with output http://ix.io/16c

After some help in the irc channel I've found the problem to be related to the calls to poll_one having no work to do, so subsequent calls to poll_one are invalid, as per http://www.boost.org/doc/libs/1_43_0/doc/html/boost_asio/reference/io_servic... thank you for your help. As an interesting side note windows has the unfortunately incorrect behavior of working, which ends up making it look like a bug >.<;;;
