Segmentation fault in Mesa dri / SDL _ConvertX86p32_8RGB332

[gatopeich]

1.- Start gltron with Mesa dri (savage dri driver on a Savage/IX8).
2.- Menus will appear allowing you to set up a game.
3.- Hit "Start game"
-> Seg fault at savage_dri.so

* Happens with other games (e.g. Armagetron), but not all, (e.g. X-moto).
* Could be a bug in SDL, 2nd thread is caught within SDL's _ConvertX86p32_8RGB332.

This should probably be forwarded upstream. Which version of ubuntu do you have? Hardy alpha1 will be released this week, and you could try the live-cd to reproduce the bug. Hardy has mesa-7.0.2 which is the latest released version.

The problem seems to reside in "read_rgba_span_x86"

There is a recent bugfix for it, see:
http://sourceforge.net/mailarchive/message.php?msg_name=200711052157.08951.bensberg%40justemail.net

Related bug upstream is:
https://bugs.freedesktop.org/show_bug.cgi?id=12614

This bug is fixed in Mesa 7.0.2
http://www.mesa3d.org/relnotes-7.0.2.html -> "Fixed MMX 565 rgb conversion problem (bug 12614)"

I will apply the patch in my system and see what I get...

Fixed with the patch for bug 12614, which is included in mesa-7.0.2
