Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- See Also| |http://bugzilla.opensuse.or | |g/show_bug.cgi?id=1187254 --- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- N.B. this fixes a problem when using libstdc++ 11.1 headers with Clang 9, where the __has_cpp_attribute(no_unique_address) test was true, but the [[__no_unique_address__]] attribute was not recognized and so was ignored, resulting in layout changes for std::tuple.
