[boost] [test] Test failures for gcc 4.6

Hi, I'm seeing these test failures for gcc 4.6 (MinGW): http://www.boost.org/development/tests/develop/developer/output/igaztanaga-d... Looks like the error originates from Boost.Test, and I can also see lots of failures in Boost.Test itself for that compiler. Is this a known problem? Any fixes planned?
