           Summary: wined3d:Farcry demo crashes in wined3d
           Product: Wine
           Version: CVS
          Platform: PC
               URL: http://www.gamersnet.nl/demos/demo.php?id=490
        OS/Version: Linux
            Status: UNCONFIRMED
          Keywords: download
          Severity: normal
          Priority: P2
         Component: wine-directx
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: xerox_xerox2000 at yahoo.co.uk


Hi, the demo runs quite nice in opengl mode so i thought would be a good test case 
for tracking down directx bugs. The demo crashes with a popup messagebox: "block
header was corrupted."

Last line in the console was:
fixme:d3d:IWineD3DVolumeImpl_LockBox (0x7c6b0c50) : pBox=(nil) stub

Following hack makes FarCray get past this bug:
in wined3d/volume.c add this line after line 144:
    FIXME("(%p) : pBox=%p stub\n", This, pBox);
if(!pBox) return D3DERR_INVALIDCALL;

The hack is probably bogus as well, but at least shows there's a bug in
IWineD3DVolumeImpl_LockBox.
How could i test this further?

(BTW. with the hack i get into the menu, but the text is unreadable, and then
FarCry crashes as it tries to load the game.)
