Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |paolo.carlini at oracle dot com --- Comment #28 from Paolo Carlini <paolo.carlini at oracle dot com> --- Something is going wrong here: the bug is closed as fixed, but if I try to enable in 20_util/common_type/requirements/sfinae_friendly_1.cc the lines which require the bug to be fixed to pass, I'm still seeing a failure, for the line: static_assert(is_type<std::common_type<const Ukn&&, volatile Ukn&&>, Ukn>(), ""); Maybe Daniel or Jason can clarify??
