3652,App Verifier issue found in  boost 1.33.0 thread library while unloading DLL,ravisingh_id@…,Anthony Williams,"DLL built using boost 1.33.0 thread libraray has Appverifier crash while unloading.


=======================================
VERIFIER STOP 00000202 : pid 0x15A4: Freeing heap block containing an active critical section. 

                06762FE0 : Critical section address.
                004D2654 : Critical section initialization stack trace.
                06762FC0 : Heap block address.
                00000040 : Heap block size.

=======================================

In file …\boost_tp\boost\libs\thread\src\tss_hooks.cpp

on_process_enter() function calls  init_threadmon_mutex()acquires memory for mutex by executing threadmon_mutex = new boost::mutex;  statement.
However, this memory is not released when dll in unloaded.  I guess the acquired memory should be released in on_process_exit() call.

Is this a known issue and is there any fix for this?
