PH25815: IGZCXCC processing fails CEE3537S cancelling a COBOL NORENT program linked RENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The dynamic call/cancel routine IGZCXCC fails with
  
      CEE3537S The request to release the WSA was unsuccessful
  
  when cancelling a COBOL program compiled NORENT but linked RENT.
  A NORENT program has all its static storage internal to the
  executable, so there's no WSA to free.
  

Local fix

• Link NORENT programs as NORENT.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL releases running   *
  *                 programs in an environment where the same    *
  *                 COBOL V5+ program compiled with NORENT is    *
  *                 dynamically called multiple times, by COBOL  *
  *                 V5+ as well as COBOL V4.2 and prior          *
  *                 releases, and then cancelled.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: During CANCEL, COBOL application        *
  *                      terminates with diagnostic message      *
  *                      'CEE3537S The request to release the    *
  *                      WSA was unsuccessful.'.                 *
  ****************************************************************
  * RECOMMENDATION: Install the provided PTF.                    *
  ****************************************************************
  When the same NORENT COBOL program is dynamically called
  multiple times by COBOL V5+ and prior releases, The program's
  runtime control block becomes incorrect; in particular, the WSA
  (Writable Static Area) address is corrupted.
  
  Later, when the NORENT COBOL program is cancelled, an error is
  encountered when freeing the WSA. This leads to diagnostic
  message CEE3537S.

Problem conclusion

• The COBOL Runtime has been fixed to address the scenario, and to
  update the program control block correctly.
