Summary: Thread safety bug in winex11.drv on exit
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The following program crashes with wine-cvs but executes fine in Windows:

int main(int argc, char* argv[])
{
    HMODULE hkernel32 = GetModuleHandle("kernel32.dll");
    FARPROC exit_process = GetProcAddress(hkernel32, "ExitProcess");
    CreateWindow("STATIC", 0, WS_VISIBLE, 100, 100, 300, 100, NULL, 0, 
NULL, 0);
    CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE) exit_process, 0, 0, 0);
    while(1) Sleep(5000);
    return 0;
}

exe and backtrace attached.

I noticed bug 5346 and believe this is a different bug because gdi_display is 
already initialized in this crash.
