--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC 6+ produces:
<source>: In instantiation of 'decltype (foo<T>()) bar(T) [with T =3D int;
decltype (foo<T>()) =3D int]':
<source>:13:8:   required from here
<source>:10:1: warning: no return statement in function returning non-void
[-Wreturn-type]
 }
 ^

And no calling of the static_assert .=
