--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
  // Override for memory_resource::do_allocate
  void*
  unsynchronized_pool_resource::do_allocate(size_t bytes, size_t alignment)
  {
    const auto block_size = std::max(bytes, alignment);
    if (block_size <= _M_impl._M_opts.largest_required_pool_block)
      {
        // Recreate pools if release() has been called:
        if (__builtin_expect(_M_pools == nullptr, false))
          _M_pools = _M_impl._M_alloc_pools();
        if (auto pool = _M_find_pool(block_size))
          return pool->allocate(upstream_resource(), _M_impl._M_opts);
      }
    return _M_impl.allocate(bytes, alignment);
  }

Yes that code looks wrong for the pool case. It does not take into account the
alignment.
