> Does 4.1 have the check for EDGE_CRITICAL_P in insert_aux?

Yes:

                          /* This can happen in the very weird case
                             that our fake infinite loop edges have caused a
                             critical edge to appear.  */
                          if (EDGE_CRITICAL_P (pred))
                            {
                              cant_insert = true;
                              break;
                            }
