I'll add more details as they unfold, but wanted to get this posted into bugzilla. The autotester has been pretty flaky lately that I don't have a good idea when this broke, but looks to have broken somewhere between Oct 29 and Nov 4. I don't have data between those dates, but Nov 4. build did not compile mesa. SegFault doesn't happen at -O1.
