------- Comment #8 from [EMAIL PROTECTED] 2007-10-24 04:45 PST -------
I tried several time to get a trace but I failed (maybe only the app/mesa is
freezing, not the server itself).
Anyway, the problem seems to go away once mesa is compiled with -O1
We are compililing mesa with gcc-4.2.2 (but the bug already
existed when compiled with prior gcc releases) at -O2 level with:
- -fno-strict-aliasing
strict aliasing is known to break some Mesa code

- -fno-tree-vrp
tree VRP in gcc-4.2.1 triggers misrendering in Blender,
and hard lock with compiz (in r300_state.c)

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32544
But it looks like it's not enough for r200 cards...
