What is a proper behavior for G++ in this case ?

should it always align std::atomic object of size 8 at 8 bytes ?

Or should G++ just never inline implementation for atomic routine ?

(see bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65149 when implementation
of atomic routine was inlined for incorrectly aligned atomic object, which
leads to BusError)
