Error description

• IBM Rational Developer for System z - RDz
  
  Attempts to Show In > Program Control Flow for some
  programs fail.
  
  This is a regression of APAR PI13945.
  
  This works in v9.5.1+iFix1, and iFix2.
  
  But, it fails on v9.5.1.1, v9.5.1.2, v9.5.1.3 and v9.5.1.4.
  
  The errors in the .log file are:
  !ENTRY com.ibm.systemz.cobol.analysis
  !MESSAGE Excessive control flow iterations:

Local fix

• none available
  

Problem summary

• The algorithm for the Control Flow walk was performing excessive
  iterations unnecessarily.
  

Problem conclusion

• The algorithm for the Control Flow walk was improved.
  
  The problem listed in this APAR has been resolved with
