XWin.exe crashes on Windows restart

[Andreas Girgensohn <andreasg123 at gmail dot com>]

I start XWin.exe via a shortcut when logging into Windows 7 (64-bit).
Recently, I replaced my Cygwin installation with the 64-bit version.
Now, XWin.exe crashes (SIGSEGV) every time I restart or shutdown
Windows.

I produced a gdb backtrace by cancelling the restart quickly after the
problem occurred.  Additional files are attached.

(gdb) bt full
#0  0x00000001004071ea in winMsgWindowProc (hwnd=<optimized out>,
message=<optimized out>,
    wParam=<optimized out>, lParam=<optimized out>)

        pScreen = <optimized out>
        hwnd = <optimized out>
        message = 22
        wParam = <optimized out>
        lParam = <optimized out>
#1  0x0000000077139bd1 in USER32!TranslateMessageEx ()

#4  0x0000000000000000 in ?? ()

On a different note, when running gdb, I noticed that XWin.exe twice
receives a SIGSYS when starting.  That does not affect normal
operations.

Please let me know if you need additional information.
