Description Dave Airlie 2005-01-27 02:36:41 UTC 
With latest CVS (drm/Mesa/xorg) get euphoria from the rss glx screensaver package,

Run it, run gears, drag gears over top of euphoria, euphoria segfaults...

I'll attach a backtrace.

May be a duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=2317 which I
reported against the Mesa product (because the code in question is outside the
driver itself).

If it is a duplicate, then it shouldn't matter whether it's a glxgears or any
other window you move over euphoria. As a workaround try defining MESA_NO_ASM=1
in the environment.

Mass version move, cvs -> git
