--- Comment #5 from Mikael Pettersson <mikpe at it dot uu.se> 2011-06-25 12:23:48 UTC --- I can't reproduce the runtime failure with gcc-4.6-20110621 on x86_64-linux. I see you're using Gentoo's modified gcc-4.4.5. Can you please try again with a g++ built from vanilla unmodified gcc-4.4.5 (or later 4.4.x) sources?
