--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Off topic, in your test you have:

   // needed for gcc
   template <typename U>
   struct rebind { using other =3D allocator<U, COPY, MOVE, SWAP, false>; };

Isn't that needed always? allocator_traits can only provide a default rebind
for an allocator "of the form Alloc<U, Args>, where Args is zero or more ty=
pe
arguments". Your non-type template arguments prevent that from working.=
