--- Comment #6 from David Krauss <potswa at mac dot com> 2010-09-30 10:15:56 UTC --- (In reply to comment #5) > Challenging to the codecvt?!? Isn't this a *char* testcase? Oh, my bad. I thought constraint_filebuf included that automatically. Guess not. I've got codecvts on the brain right now. So yeah, there's really nothing remarkable at all about this testcase. Quite a random failure. Are you still CC'd here Paolo?
