Hello, My questions are: 1) Is there any ETA for releasing a fix? 2) Otherwise, is there an recommended fix I can apply myself? Environment: * MSVC 8.0 * boost v1.33.1 It seems that it's a known issue that has been present for quite a while (at least since 1.30): "Perhaps this is the same leak reported by gast128 in the thread "Memory leak reported using threads library". A mutex is created in DLLMain -> on_process_enter -> init_threadmon_mutex. It seems that this mutex is never deleted and there is no comments that this is intentional. On Windows the size of the mutex is 8 bytes and it creates a CRITICAL_SECTION in its constructor - 24 bytes." I'm not concerned much by the size of the leak nor the semantics of whether it is truly a leak. My concern is that I'm receiving an alert from VS indicating "Detected memory leaks!" and regardless of how MS's detecting this, it's obviously not a good situation for me. Regards, Jason
