Hi All,
The problem with xm_tri.c and xlockmore is still present on my VMS-box. I have
a patch that prevents mesa from crashing, but Brian liked to have some more
data. I did send them over a month ago. Could anybody reproduce the problem
or are we going to put my patch in the distribution and noth bothering
anymore about the cause of the crashes.
