Direct3D8 regression/bug

[Roderick Colenbrander]

Hi,

Just to see how well Wine's Direct3D8 support is working, I played with some 
some simple d3d8 demos. (that are the tutorial examples Jason Edmeades used 
when he started Wine's Direct3D8 implementation) A few weeks ago all those 
demo's worked. Perhaps some things where not rendered correctly but they 
worked.

A few days ago I rechecked those demo's but now all d3d8 apps I try crash. 
Immedeately winedbg is launched. The app seems to crash in libGL.so.1. 

Here's the error with a backtrace:

Unhandled exception: page fault on read access to 0x00000008 in 32-bit code 
(0x40bf4a06).
In 32-bit mode.
0x40bf4a06 (_end+0xf6a9a in libGL.so.1): movl   0x8(%eax),%eax
Wine-dbg>bt
Backtrace:
=>0 0x40bf4a06 (_end+0xf6a9a in libGL.so.1) (ebp=00000001)

Lionel suggested that his OpenGL patches may have caused this problem. He had 
the same crashes on his pc. I reversed his patches but it still had problems. 
(perhaps I made some misstakes somewhere ..)

Perhaps the problem is related to the OpenGL drivers. I'm using Nvidia's 
OpenGL drivers (1.0-3123). 

I hope this helps a bit,
