Summary: Library initialisation crash with USER and X11DRV
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Keywords: download, source
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This simple program crashes Wine:

#include "windows.h"

int main(int argc, char * argv[])
{
  static const WCHAR szDisplayW[] = { 'D','I','S','P','L','A','Y','\0' };
  HDC dc = CreateDCW(szDisplayW, NULL, NULL, NULL);
  DeleteDC(dc);
  return 0;
}

This happens:

- CreateDCW wants to load X11DRV
- USER attaches to the process and registers its builtin window classes. It 
also loads a cursor for a window class
- LoadCursor calls CreateDCW again
- This time Wine thinks that X11DRV is already loaded
- CreateDCW calls X11DRV_XRender_Init() which uses the variable gdi_display. 
But this variable is uninitialized because X11DRV's DllMain has not been 
called.

I hope that somebody can help.
