--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-03-12 13:43:35 UTC --- Do I understand correctly that in N3291 the destructor lost the explicit noexcept simply because of core/1123? In that case I think that in GCC we should mark it temporarily noexcept and then remove it in mainline when c++/50043 will be addressed (I mean to work on it over the next weeks). 4_7-branch will not change anymore.
