           Summary: winecoreaudio memory management and locking
           Product: Wine
           Version: 1.3.37
          Platform: x86
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: normal

    Classification: Unclassified

Running my render tests in a loop sometimes causes an endless sequence of
errors

wine(4470,0x40805a00) malloc: *** error for object 0x4022e310: double free
*** set a breakpoint in malloc_error_break to debug

Process analysis shows that IAC_Release/DisposeQueue is involved
 1465 func_render
    1465 test_clock
      1465 AudioClient_Release
        1465 AudioQueueDispose
          1465 AQServer_DisposeQueue
            1465 AudioQueueObject::~AudioQueueObject()
  100.000%    1465 free
