--- Comment #5 from Ilia Mirkin imirkin@alum.mit.edu --- Hmmm... that did not have the desired output. Can you make sure to build mesa with --enable-debug ? I'm guessing some of the stuff is only output in that case.
Also, for your next attachment, please use xz -9 foo.log (saves a step... zip is an archive, so you have to unzip in order to see it, while with a stream compression format you can view it directly).
