            Bug ID: 44289
           Summary: Possible access to unintended field in
                    "wine/dlls/comctl32/comboex.c" line 1033
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: comctl32
          Assignee: wine-bugs at winehq.org
          Reporter: petrum at gmail.com
      Distribution: ---

While experimenting with a CodeSonar plugin we develop, we noticed a
potential bug in file "wine/dlls/comctl32/comboex.c" line 1033 function
COMBOEX_Create

SetWindowSubclass(infoPtr->hwndEdit, COMBOEX_EditWndProc, EDIT_SUBCLASSID,
                      (DWORD_PTR)hwnd);

infoPtr->font = (HFONT)SendMessageW(infoPtr->hwndCombo /*HERE*/, WM_GETFONT, 0,
0);

Shouldn't you access infoPtr->hwndEdit (instead of infoPtr->hwndCombo) at the
mentioned position in the second line?

Thanks,
Petru Florin Mihancea
