http://bugs.winehq.org/show_bug.cgi?id=20545

Summary: memory leak in MMDRV_Init on exit?
           Product: Wine
           Version: 1.1.32
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: winmm&mci
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

On several Chromium tests (having nothing to do
with multimedia?), valgrind is reporting a leak in winmm:

56 bytes in 1 blocks are possibly lost in loss record 464 of 1,033
   at notify_alloc (heap.c:214)
   by RtlAllocateHeap (heap.c:1421)
   by MMDRV_InitPerType (lolvldrv.c:419)
   by MMDRV_Install (lolvldrv.c:510)
   by MMDRV_Init (lolvldrv.c:561)
   by DllMain (winmm.c:184)
   by __wine_spec_dll_entry (dll_entry.c:40)
   by ??? (in /home/dank/wine-git/dlls/ntdll/ntdll.dll.so)
   by MODULE_InitDLL (loader.c:982)
   by process_attach (loader.c:1071)
   by process_attach (loader.c:1063)
   by attach_process_dlls (loader.c:2440)

This doesn't happen terribly often, is there something
that occasionally prevents freeing on unload?
