Error description

• A DFHFC0001 error occurs during SYNCPOINT processing.  The 0C4
  abend is occurring in DFHFCRC on a MVI instruction:  9240 202D

  ****************************************************************
  SYNCPOINT processing attempts to shunt a unit of work. DFHFCFR
  processes the UOW FLABs required. A null fcte_pointer in a FLAB
  leads to low core being updated and an ABEND0C4 in DFHFCRC as
  it attempted to turn off a bit in the FCT. This is regarded as
  a severe error and CICS terminates abnormally.

Problem conclusion

• UK09356
  
  DFHFCRC has been altered so that a validation check is done on
  the fcte_pointer to confirm it is not null. This is done at the
  beginning of procedure close_if_req_and_poss_shunt.
