--- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-11-11 01:38:40 UTC --- Apparently r181278 doesn't ICE anymore: 50473.C:14:36: error: taking address of temporary [-fpermissive] 50473.C:14:36: error: ‘* & s<0u>()’ is not a constant expression but the error message seems anyway pretty obscure and actually I don't see why the test is invalid. Jason, can you help triaging this?
