-------------------------------------------+--------------------------------
 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?

 This problem was also found in 1.34 version
