Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V5.2 compiling     *
  *                 programs with PERFORM statements that can    *
  *                 reach themselves, using INITCHECK.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: Compiler ABORT with message             *
  *                      MSGIGYCB7104-U: Internal error while    *
  *                      compiling function XXXXXX. Failed       *
  *                      assertion on                            *
  *                      analyses/Dominators.cpp:117.            *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  In some rare cases, when PERFORM statements cause infinite
  loops by reaching themselves, the code that allows INITCHECK to
  identify which data items are initialized by each PERFORM
  statement cannot properly identify which lines of code will be
  executed by a PERFORM.
  

Problem conclusion

• The compiler was modified to handle those rare cases more
  gracefully.
  

Temporary fix
