--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
François, why does __rehash_policy check for inequality?

  if (__n_bkt != _M_bucket_count)
    _M_rehash(__n_bkt, _M_rehash_policy._M_state());

Is there any reason not to change that to:

  if (__n_bkt > _M_bucket_count)
    _M_rehash(__n_bkt, _M_rehash_policy._M_state());
