--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm:

        _Bit_pointer __p =3D _Bit_alloc_traits::allocate(_M_impl, _S_nword(=
__n));
#if __cpp_lib_is_constant_evaluated
        if (std::is_constant_evaluated())
        {
          __n =3D _S_nword(__n);
          for (size_t __i =3D 0; __i < __n; ++__i)
            __p[__i] =3D 0ul;
        }
#endif

Maybe I misunderstand how this should work.=
