With MFC, memory leak?

I use dialog-based MFC program, every ice-related thing is running in a thread created by this line in OnInitDialog():
g_hthread = (HANDLE)_beginthread(RunPatch,0, &g_mypar);

then, in OnDestroy():
if (g_hthread)
::WaitForSingleObject(g_hthread, INFINITE);

At last, I find some exceptions and many memory leak items in debug window:
NetorLiveUpdateClid.exe 0x77e6a4e1 exceptionF0x000006BA: RPC server not avail B
UpdateClid.exe 0x77f81d96 exceptionF0xC0000005: read location 0xfffffffd B
UpdateClid.exe 0x77f81d96 exceptionF0xC0000005: read location 0xfffffffd
...

Detected memory leaks!

    Ice has been tested with MFC many times, and there are no known memory leaks.

    Unfortunately, with the information you provide it is impossible to say what the reason for the leak you are experiencing might be. We would need to see a small, self-contained example that demonstrates the problem.

    The problem example code

    I just want to try IcePatch in a small dialog mfc program and display a progress control.

    IcePatch's code is copy from your source code and run in a single thread.
    When thread running, I just test its existing in OnTimer, if it return from thread, I just close dialog.

    If you just run it, will see what I see...:(

    BTW:I use VC70 and attachment is whole project compress(ZIP) file. Please just give a look.

    I have no idea what memory debugger this is, but perhaps you should check your program with Purify. First purify IcePatch itself, and then your modified version.

    I don't know anything about DEBUG_NEW, and therefore cannot comment on the debug output.
  • alwayscy1alwayscy1 Member
    DEBUG_NEW is produced by VC70's project wizard. I find your Ice source code is also can be built by VC70 or VC71.
