PH14212: ABEND0C8 fixed overflow in UNSTRING verb in very rare cirumstances

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• If using UNSTRING, fixed overflow is enabled (which is not
  usually the case in a pure COBOL program) and the stack contains
  just the right residual data, there may be a fixed overflow
  abend on a LOAD COMPLEMENT (LCR) instruction trying to
  complement the value of 0x8000000.
  
  (The negative number with the largest absolute value has no
  complement.)
  

Local fix

• STORAGE(,,00) will clear the stack frame, avoiding the residual
  data, but depending on application specifics, may have
  performance implications.

  ****************************************************************
  When COBOL runtime was processing the UNSTRING statement,
  uninitialized residual data on the stack was used. Depending on
  the input and residual data, this might result in incorrect
  UNSTRING output or CEE3208S abend.

Problem conclusion

• The COBOL Runtime is corrected to initialize the stack with
  correct values.
