[Bug 20303] New: Spurious valgrind warning in HEAP_CreateSubHeap?

http://bugs.winehq.org/show_bug.cgi?id=20303

Summary: Spurious valgrind warning in HEAP_CreateSubHeap?
           Product: Wine
           Version: 1.1.29
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: download, source
          Severity: normal
          Priority: P2
         Component: ntdll
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running wine's tests under valgrind generates lots of errors like:

Invalid write of size 4
    at 0xCC5CE91: HEAP_CreateSubHeap (heap.c:815)
    by 0xCC5E643: RtlCreateHeap (heap.c:1265)
    by 0xCC95B0D: thread_init (thread.c:328)
    by 0xCC67898: __wine_process_init (loader.c:2695)
    by 0xC52E91A: wine_init (loader.c:711)
    by 0x7BF01274: main (main.c:218)
Address 0x7f00000c is not stack'd, malloc'd or (recently) free'd

Seems like ntdll is missing a valgrind annotation or two...?
