Bug #: 34084
           Summary: EnumWindows and 1.6rc*
           Product: Wine
           Version: 1.6-rc5
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: user32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I use wine to run preliminary python regression tests cross-build from linux to
windows 32

Following test fail (Segmentation fault) in  1.6rc1,3,4,5:
-----------------------
        def test_issue_8959_b(self):
            from ctypes.wintypes import BOOL, HWND, LPARAM
            global windowCount
            windowCount = 0

@WINFUNCTYPE(BOOL, HWND, LPARAM)
            def EnumWindowsCallbackFunc(hwnd, lParam):
                global windowCount
                windowCount += 1
                return True #Allow windows to keep enumerating

windll.user32.EnumWindows(EnumWindowsCallbackFunc, 0)
-----------------------

Test pass with wine version 1.5.16. Also pass with 1.6rc{1,3,4,5}  if is run in
X terminal with unset DISPLAY variable.

All above mentioned wine versions are build in one and the same environment,
i.e. compiler, packages etc.

Severity is set to  minor as "Segmentation fault" is in development
environment.
