-----------------------------------------------------------

                 Key: HARMONY-2669
                 URL: http://issues.apache.org/jira/browse/HARMONY-2669
             Project: Harmony
          Issue Type: Bug

         Environment: Windows XP i686
            Reporter: Salikh Zakirov

The attached test crashes debug version of DRLVM on a heap pointer validity check on free().

With the following stack:
 	harmonyvm.dll!_CrtIsValidHeapPointer(const void * pUserData=0x02876958)  Line 1807	C
 	harmonyvm.dll!_free_dbg_lk(void * pUserData=0x02876958, int nBlockUse=0x00000001)  Line

Running the same test with J9 produces
