[Bug 20692] New: Probable benign window title leak

http://bugs.winehq.org/show_bug.cgi?id=20692

Summary: Probable benign window title leak
           Product: Wine
           Version: 1.1.32
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: user32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This is another case of 'a leak so small it doesn't matter'.
I think it only happens once per window, and only when the 
window doesn't get an NCDESTROY message before exiting.
I'm filing it and marking it WONTFIX so the valgrind suppression
I create can point to a bug report for explanation.

http://kegel.com/wine/valgrind/logs/2009-11-11-07.36/vg-user32_msg.txt
says user32_test.exe.so msg.c leaks like this:

22 bytes in 1 blocks are definitely lost 
    at  notify_alloc (heap.c:214)
    by  RtlAllocateHeap (heap.c:1421)
    by  DEFWND_SetTextA (defwnd.c:98)
    by  DefWindowProcA (defwnd.c:834)
    by  MsgCheckProc (msg.c:7274)

And 
http://kegel.com/wine/chromium/valgrind-logs/base_unittests/MessageLoopTest....
says that base_unittests.exe --gtest_filter=MessageLoopTest.RecursiveDenial2
and a couple others leak as follows:

8 bytes in 4 blocks are definitely lost in loss record 87 of 1,034

We can reopen this bug if the leak turns out to be an actual problem.
