Any chance you could get a real backtrace with gdb?

I tried to receive a backtrace from gdb but obviously my computer skills are
not sufficient.

After reading a couple of howtos on debugging with gdb in the internet I
installed xserver-xorg-core-dbg, recompiled drm, ddx and mesa with
CFLAGS="-march=native -O2 -ggdb" (and aditionally configured mesa with
--enable-debug running ./autogen.sh).

However on calling glxinfo within gdb I still get:

"Reading symbols from /usr/bin/glxinfo...(no debugging symbols found)...done."

Sorry, it seems as though I cannot contribute anything useful at the moment.

Best regards,
Heinrich

That should be okay, so long as it can get debugging symbols for r300_dri.so.

No bug but a user mistake.

I had not configured the respective mesa code with
--with-dri-drivers=radeon,r200,r300,r600 as proposed in radeonBuildHowTo but
had assumed that configure option --with-dri-drivers=radeon was ok for my r500.

So an older version of r300_dri.so was in my /usr/lib/dri/ which probably
caused the segfault.
