With mesa 7.0, radeon driver for an ati 9600 XT, everytime I start glxgears, X crash, the same happens when I run just gears.
I am using Option "NoAccel" "1" in my xorg.conf. When I used acceleration, some other programs were crashing X - xine for example.
attaching xorg.conf, xorg.log, strace and gdb log of the crash

$ ltrace -f -i -n 2 -o ltracegears -s 1024 -S -t /usr/bin/gears
With NoAccel, you're not using dri. Only the mesa version which you've compiled your xorg server against thus matters (if you've compiled your xorg server from git, I've seen a couple versions which broke indirect rendering completely, these things do happen). Moving to mesa/glx, though maybe it should rather be xorg/lib/glx.
does not happen when AGP is set to 4x in the xorg.conf

Have you removed the NoAccel line? I fail to see how that AGP line can make any difference without Accel enabled. Please don't mix different issues.

yes, I the NoAccel line is no longer there
What is the AGP transfer rate set to in the BIOS setup, and any other AGP related settings? Also, please attach a log file from starting the X server without Option "AGPMode".

Hi, there is no AGP rate setting in the BIOS
Anyway, in the meantime I took inspiration in blino's blog about solving similar problem (http://blino.org/blog/mandriva/composited-desktop/compiz-gconf-mesa-gcc.html) -
https://bugs.freedesktop.org/show_bug.cgi?id=11380, which is apparently caused by gcc bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32544.
So I asked him to provide mesa packages built with no gcc optimizations and the problem went away.
I also tested mesa built with -O1, which were almost OK - glxgears running, 3d games running, but I got an X.org freeze when resizing a window in jedit.
*** This bug has been marked as a duplicate of bug 11380 ***
It's not exactly the same as bug 11380, since even building with -O1 triggers the crash here.
There must be some additional problem, but I can't tell yet if it comes from mesa or from gcc.
Definitely not the same as 11380 because 11380 doesn't crash the X server -- it just garbles the output.
Do you still have this issue with more recent mesa ?
Mass version move, cvs -> git
