Sorry, I don't know. I updated Mesa to the latest Git version and got a
segfault when any OpenGL program starts.

The segfaults is in src/gallium/drivers/r300/r300_context.c:425
(r300_create_context). GDB said that the line 425 is segfaulting :

425 r300->cs = rws->cs_create(rws);

I explored the values of some variables, r300 is ok, rws is ok and
rws->cs_create seems to contain an address in r300_dri.so. I don't know why it
is segfaulting.

I will try to bisect Mesa to see when it happened, but I now have to disable
GLX in my xorg.conf to have Xorg starting without segfaulting. I am unable to
launch any GL program, so it will take some time. For now, the only commit I
think can be responsible of this segfault is
a508d2dddcc67d0f92cc36b9ed6f36a9bbfc579d (gallium: introduce get_shader_param
(ALL DRIVERS CHANGED) (v3)). It adds an entry in r300screen, but I don't know
if it is possible that it is related to my segfault.
