--- Comment #1 from HaoChen Gui <guihaoc at gcc dot gnu.org> ---
   bool always_stored = ref_always_accessed_p (loop, ref, true);
   if (maybe_mt
       && (bb_in_transaction (loop_preheader_edge (loop)->src)
           || (! flag_store_data_races && ! always_stored)))
     multi_threaded_model_p = true;

Could we consider multi_threaded_model_p here is false for a local auto
variable?
