Server failing when BOOST_ASIO_ENABLE_HANDLER_TRACKING is active
Trying to track down when the socket closes on my program, I turned on asio debugging. Server fails when BOOST_ASIO_ENABLE_HANDLER_TRACKING is active.

I guess you've got an ODR violation, and this is the root of all the issues you encounter. Check thoroughly all the #ifdef's and #define's you have in every translation unit.

I spoke too early. I removed all debugging code from asio and it does not crash anymore. Attached are the new logs, which show nothing in particular. Maybe someone can see something missing.
I have the same problem when defining BOOST_ASIO_ENABLE_HANDLER_TRACKING. My io_services are simply returning. like if there was no event to process. When I remove the define, it runs well. On Thursday, 3 January 2013 21:12:40 UTC, Gonzalo Garramuno wrote:

Ok, I think I got it! You have to define the BOOST_ASIO_ENABLE_HANDLER_TRACKING in every module that uses Boost. I was only defining in one and that may be the reason why io_service was returning (or crashing, don't know). What I know is that I defined BOOST_ASIO_ENABLE_HANDLER_TRACKING in all my modules and now I have tracking are proper program execution. Hope it helps!

This is true for most macros that alter behavior. Because they usually modify the definition of inline and template functions, and multiple definitions of external linking functions with different definitions is an One Definition Rule violation.
Hope it helps!
