Hmm:

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

Maybe I misunderstand how this should work.
