The user32/win test crashes X on Intel cards

[Francois Gouget]

I hit this issue while trying to run winetest for WineConf. I looked 
into it and the crash is caused by this line in dlls/user32/tests/win.c:

SetWindowPos(hwnd, 0, 32768, 40000, 32768, 40000, SWP_NOMOVE);

More precisely it's the setting of the window width and height to 
32768 x 40000 that causes the crash. Looking at the .xsession-errors 
file I see the window manager reporting the following X server error:

Anomalie dans le gestionnaire de fenêtres : Unexpected X error: BadAlloc 
(insufficient resources for operation) serial 11940 error_code 11 
request_code 53 minor_code 0)

Is it possible that this is just an out of memory issue caused by the 
huge window size? According to my tests 32000x32000 (a tad < 3GB) works 
but 32767x32767 (a tad >3GB) cause the crash.

Here's my configuration:
 * Intel Corporation Mobile 945GME Express Integrated Graphics Controller rev 3
 * VideoRAM: 256MB (according to /var/log/Xorg.0.log)
 * xserver-xorg-video-intel 2:2.9.0-1
   Latest from Debian Testing.
   Debian Unstable does not seem to have a more recent driver.

Marcus got the same issue and he had an Intel card too and we were the 
only two with this issue. So apparently this is Intel-specific.

Does any one have an Intel card where this does not happen? What's your 
driver version?

This happens on Mac OS X, too. Check out

More data:
 * Marcus is running version 2.9.1 of the Intel driver (and gets the 
   crash).
 * Michael Stefaniuc does not have the problem. He is using FC11's 
   2.8.0 version of the driver.
 * I tried Michael's FC11 intel_drv.so file on my system and I still 
   get a crash. I also tried the 2.8.1 Ubuntu driver and got the same 
   result. So the problem comes from some other part of Xorg or the 
   kernel.
 * Michael is running the 2.6.32 kernel and I'm running the 2.6.30 one.
