--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I've raised this for discussion with LWG.
FWIW libc++ and MSVC reject the example too. It looks like everybody treats
P0558 as a DR.
It's valid as C++11 and C++17, with old and new implementations, if changed to
use std::atomic_fetch_add(static_cast<std::atomic<int*>*>(*ap), 1); }
i.e. using an explicit conversion instead of an explicit template argument
list.
