Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• PROBLEM DESCRIPTION:
  When compiling COBOL programs that
  contain level 88 condition names, the
  compiler can crash with messages
  indicating the Language Environment
  heap structures have been damaged or
  corrupted, or the compiler can ABEND
  with system abend code S0C4.

  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  In some rare instances, the presence of a level 88 condition
  name exposes memory overlay bug in the compiler that manifests,
  at COBOL program compilation time, as a Language Environment
  heap corruption crash.
  

Problem conclusion

• The memory overlay problem was corrected in the compiler,
  thereby fixing the cause of the problem.
