I also see this same crash on another game Eternal Lands (which is not in Ubuntu but there is a need packaging bug #335038).

Anyway, I have traced the crash to a call to glCopyTexImage2D():

glCopyTexImage2D (GL_TEXTURE_2D, 0, GL_RGBA, 0, 0, bg_width, bg_height, 0);
where bg_width=1024 and bg_height=512.

There error message is the same:
intel_tex_image.c:355: intelTexImage: Assertion `texImage->RowStride == postConvWidth' failed.

The machine is a dell laptop containing an "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)". I had booted from the 9.04 Jaunty live CD and installed the packages necessary to compile and run the Eternal Lands game. There have been several reports on the game forums of crashes with Jaunty and intel cards which is why I investigated; I had to borrow the machine as I don't have another with Intel graphics.

A simple test case

Actually this bug is rather easy to reproduce, any call to glCopyTexImage2D will trigger it if the requested texture width exceeds OpenGL window width, however any height is ok.
I have attached a simple test case for this.

In addition, if you allocate memory for the texture with something like this before operation:
glTexImage2D (GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_BYTE, NULL);
...glCopyTexImage2D function succeeds.

I have used Intel drivers 2.7.1 and Linux 2.6.30.

It sounds like the driver is allocating the texture based on the clipped-to-window size instead of the requested size.

Clip size after allocating the texture

Try this patch. If it fixes the problem, I'll push it to master and the various stable branches.

Hi,

any chance this could be applied to mesa_7_4_branch?

The bug is pretty annoying so it would be nice to have it fixed in distros ASAP.

Thanks
