@erichkeane - I took your example and tried to reduce it further

It's kind of a difficult situation - both gcc and msvc accept it, yet /* very very cautiously */ it might happen that the code is actually invalid ...
(i'd need to think about it more), but this is based on the insights from @rsmith  and http://eel.is/c++draft/temp.constr#atomic-3.sentence-5 .
