Comment (by hinder):
From the wiki page, a conclusion might be that in newer versions of gcc, fast-math may be much more aggressive, and cause the GRHydro.GRHydro_test_shock_weno/1procs test to fail. Older versions with ubuntu.cfg (and hence fast-math) seem to work, whereas newer versions don't. Omitting fast-math on the newer version also works. We talked on the call about possibly making the optionlists more conservative to avoid all the time spent on these sorts of problems, but we would like to see benchmark results before making such a decision.
