Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IGZXAPI function 7 fails to call the callback provided by Fault
  Analyzer to map addresses in a mini-dump when following the link
  from the CEEBETBL to the CEEBLLST, leading to a bad memory
  reference.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 5 and later        *
  *                 releases running programs which call         *
  *                 IGZXAPI with function code 7                 *
  *                 (CWSA Address Query with callback).          *
  ****************************************************************
  * PROBLEM DESCRIPTION: A call to IGZXAPI with function code    *
  *                      7 may lead to an 0C4 abend or           *
  *                      incorrect output values.                *
  ****************************************************************
  * RECOMMENDATION: Install the provided PTF.                    *
  ****************************************************************
  When IGZXAPI was called with function code 7 with a callback
  function as one of its arguments (XCBACK7), it may lead to
  an 0C4 abend or incorrect output values due to bad memory
  reference.
  
  Call to IGZXAPI without a callback function(XCBACK7) is not
  affected by this problem.

Problem conclusion

• The error in the COBOL Runtime has been corrected. The problem
  was resolved by taking the callback function into consideration
  to avoid bad memory reference. When the CWSA Address cannot
  be queried, a NULL (address of 0) is set accordingly.
