           Summary: Bug in enhmetafile.c
           Product: Wine
           Version: unspecified
          Platform: All
        OS/Version: other
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: wine-gdi
        AssignedTo: wine-bugs(a)winehq.com
        ReportedBy: rspilon(a)rogers.com


There is an error in enhmetafile.c - the code:

 case EMR_SCALEVIEWPORTEXTEX:
      {
        PEMRSCALEVIEWPORTEXTEX lpScaleViewportExtEx = (PEMRSCALEVIEWPORTEXTEX)
mr;

        if ((info->mode != MM_ISOTROPIC) && (info->mode != MM_ANISOTROPIC))
	    break;
        if (!lpScaleViewportExtEx->xNum || !lpScaleViewportExtEx->xDenom || 
            !lpScaleViewportExtEx->xNum || !lpScaleViewportExtEx->yDenom)
            break;

Notice - the line just before the break above - it should be:

!lpScaleViewportExtEx->yNum ( and not xNum )
