--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
Btw, ref_may_access_global_memory_p already checks

      if (!auto_var_in_fn_p (base, current_function_decl)
          || pt_solution_includes (&cfun->gimple_df->escaped,
                                   base))

so it seems it was aware of some issue.  I'm testing some patch.
