But, despite us now being on the same version of gcc, Dirxion and OSL results are not the same. The bind library went to green like OSL's. But the optional and spirit libraries remained green with the gcc upgrade, while OSL is yellow on those libraries. The difference in the "optional" library is because of the differences in toolset names. Some of the tests are marked as expected failures for gcc-3_3-darwin but not darwin. I'll change my toolset name to match yours so that these go away. The Spirit failure is actually a failure. I get: Courier No errors detected. /Volumes/scratch/dgregor/BoostRegressionTesting/boost/libs/thread/src/mutex.cpp:211: failed assertion `res == 0' Doug, we're now on the same exact compiler so I'm not sure what would be different between our setups except that I'm on 10.3.9 and you are on 10.3.8. I really don't know what in the OS update would have to do with this. Do we have some other difference? Yep... I'm running a dual-processor G5. The spirit test that's failing for me but not you is "owi_mt_tests", and I'm guessing that "mt" is "multi-threaded". Sounds like an actual bug in Spirit or Thread. Doug
