Which versions of GCC are you using?
The two gcc versions are the 4.1 (miscompiles) and 3.4 (OK) from Debian unstable. I had originally compiled it myself with gcc-4.1 because the Debian libgl1-mesa-dri package didn't build i965_dri.so until I submitted a build patch to them to have it built. They released a new package a few days ago with i965_dri.so included, presumably built with the same gcc-4.1, the default cc on Debian unstable. I had exactly the same problems with my own version and theirs. I rebuilt it again today with CC=gcc-3.4 and now everything works great. I saved a copy of the old i965_dri.so, so I can verify in the next few days that replacing it breaks things again. Let me know if you want copies of these files to examine. -ryan ------------------------------------------------------------------------- Using Tomcat but need to do more?
