--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-08-12 16:22:28 UTC --- I need a ChangeLog entry before I can commit the change, which needs your name, could you provide a ChangeLog entry? Thanks. Unless I'm mistaken the volatile qualifiers in the testcase don't serve any purpose, so I've removed them from the patch I plan to commit. I have seen it fail, but can't make it fail now, but I think it's useful to commit anyway.
