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
Created attachment 10727 [details] xorg.conf
Created attachment 10729 [details] strace
Created attachment 10730 [details] gdb output
Created attachment 10731 [details] another gdb output seems that when I step through more slowly, glxgears crash a bit later
Created attachment 10732 [details] xorg log
Created attachment 10764 [details] ltrace output of $ 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
(In reply to comment #8) > 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.

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".

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
