Hi everyone, I recently ran into a problem with Boost.Asio while using a slightly modified version of the HTTP 2 example server. The debugger trace (attached) shows where a segfault had occurred in the code. The short of it is that when ~wrapped_handler is called, the call to boost::detail::atomic_exchange_and_add fails when boost::detail::sp_counted_base::release is invoked. It occurs when a handler_wrapper is deleted/destructed (~handler_wrapper is called) in the strand_service. I'm just wondering what could be causing this -- it's worth noting that under not-so-heavy load, the problem does not manifest itself; but soon enough when the load on the server goes up (more incoming connections) the server crashes consistently. Any pointers where I should be looking? I'm using Boost.Trunk revision number 43296. -- Dean Michael Berris Software Engineer, Friendster, Inc.
