--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The fix for the code is simple though:
std::array<std::byte, N> ret{};
That is value initialize ret.
In C++17, uniniitialized variables are supposed to be rejected so this is
accepts invalid for <=16 too.
C++20 allows uninitialized variables to begin with as long as they are fully
initialized at the end of the full constexpr expression.
