Re: [Mesa3d-dev] crash in current CVS version
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.
