--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Since the value that is done in the static_assert is not value dependent, it is
rejected at the definition time of C<T>::C<T>.
This is correct.
Can you use either do the following instead:
template <typename T> struct C
{
C(T) = delete;
};
Which requires a specialization for C<T>::C<T> so it will not be a deleted
constructor.
