PH41810: ABEND0C1 branch to zero calling via the procedure-pointer returned from a CALL RETURNING procedure-pointer

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Code to sanitize the returned procedure-pointer mistakenly sets
  the target address portion of the procedure-pointer to NULL, and
  the second word to the address of the compiler temporary used to
  receive the returned procedure-pointer.
  
  A subsequent call using the procedure-pointer will branch to
  location zero.
  

Local fix

• Use a function-pointer instead.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.3 compiling and  *
  *                 running programs that contain a CALL         *
  *                 statement with RETURNING phrase that         *
  *                 specifies a receiver of USAGE                *
  *                 PROCEDURE-POINTER.                           *
  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect PROCEDURE-POINTER value,      *
  *                      which can result in a S0C1 abend when   *
  *                      used in a CALL statement.               *
  ****************************************************************
  * RECOMMENDATION: Apply the IBM-provided PTF.                  *
  ****************************************************************
  The compiler was generating incorrect code to store a
  PROCEDURE-POINTER value returned from a program into a user's
  receiver data item.
  

Problem conclusion

• The compiler was updated to generate correct code to store a
  PROCEDURE-POINTER value returned from a program into a user's
  receiver data item.
