    Description

      QAxConnection class is poorly designed. When a connection point enumerator is requested it returns a pointer to itself. As a consequence all connection point enumerators of the same object share the same state. Calling Reset of any enumerator resets states of all.
      Enumerator iterator is not initialized when enumerator is requested. Calling IEnumConnections->Next without IEnumConnections->Reset causes a crash in iterator dereferencing.
