It doesn't add up. The "start" parameter in draw_elements is 117825309, it's
impossible for the index buffer to be so large. I might add some validation in
the draw function for it not to crash, but that would just hide problems
elsewhere.

I'm sorry for not responding. I now tried with current git (version
5fa1af0905ef2f513fe296f1d8e658dbdf24dd74), and it still prints
r300: Invalid index buffer range. Skipping rendering.
upon certain objects entering the view (like the giant walker, the cupboards in
the houses and in the tunnel etc.).

Is this still an issue with Mesa 7.9 or the latest version from git?

Yes, the problem still exists. It doesn't crash; though, because Marek added a
hack that disables rendering instead of crashing.

Created an attachment (id=41442)
 View: https://bugs.freedesktop.org/attachment.cgi?id=41442
 Review: https://bugs.freedesktop.org/review?bug=28623&attachment=41442

etqw_crash_fix.patch

The attached hack may not be correct, but it fixes this problem. When drawing
light halos around lamps, etqw calls glDrawElements() as it was issuing a
vertex array: indices is a pointer to the buffer rather than an offset to the
vbo. The real bug may be in etqw (is it allowed to issue a vertex array while a
vbo is bound?) or in the way mesa detects the difference between a vertex array
and a vbo. Or in the head of the one who designed glDrawElements() this way...

Could you possibly bring this issue and the patch to the mesa-dev mailing list?
I can't comment on something I can't reproduce and this seems to be quite
special. Maybe the Mesa maintainers will know what is going on. I don't think
that patch is going to be accepted, but at least it's a good starting point.

OK, I subscribed to mesa-dev, and will post this issue shortly.

Meanwhile, to increase reproducibility: I'm testing with the demo, which is
ETQW 1.4.12343.12343  linux-x86 Jan 16 2008 10:19:41
Maybe the retail version does not trigger this crash (?)

I now purged and reinstalled the game (with the same installer as before, which
has the correct md5sum), and the problem is gone (and so is #32652). I forgot
to keep a copy of the previous install, though, so I don't know what's
happened.

Now this problem appeared again, and I was able to investigate it.
In .etqwctl/base/etqwconfig.cfg the correct setting is
seta r_useIndexBuffers "1"
and the incorrect is "0". I still don't know why, when, or how this was changed
automatically.
