PH59549: Assertion at ilgen/z/WCodezOSSystemOSLinkage.cpp on FUNCTION function-name(ADDRESS OF some-item)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The compiler front end doesn't properly represent ADDRESS OF
  parameters to various intrinsic functions like BIT-OF and HEX-OF
  in the intermediate language, leading to the back end assertion
  in WCodezOSSystemOSLinkage.
  

Local fix

• Set a pointer to the ADDRESS OF some-item, and use the pointer
  in the function call.

  * RECOMMENDATION: Apply the provided PTF                       *
  ****************************************************************
  When the argument of the HEX-OF/BIT-OF intrinsic function was of
  the form ADDRESS OF <unbounded table>", the compiler was
  inadvertently treating the result value as being dynamic in
  length instead of having a fixed length.
  

Problem conclusion

• The compiler was updated so that when an argument of the form
  "ADDRESS OF <unbounded table>" is used in the HEX-OF/BIT-OF
  intrinsic function, the result value is understood to be fixed
  in length.
  

Temporary fix
