Sometime the ASCONF_ACK parameters can equal to the fourfold of
ASCONF parameters, this only happend in some special case:

  ASCONF parameter is :
    Unrecognized Parameter (4 bytes)
  ASCONF_ACK parameter should be:
    Error Cause Indication parameter (8 bytes header)
     + Error Cause (4 bytes header)
       + Unrecognized Parameter (4bytes)

Four 4bytes Unrecognized Parameters in ASCONF chunk will cause panic.
