--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I thought all the bits of the type are padding bits (given that reads of
std::nullptr_t typed objects just don't read any of the bits and simply result
in nullptr).
So, I think most likely the first __builtin_bit_cast should be rejected in
constexpr contexts and the second one accepted.
