APAR status

• Closed as program error.

Error description

• When compiling a specific test case that has -qipa and -g
  enabled, the compiler abends.
  

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  Users of TPO with -qipa and -g may be affected by this issue.
  
  PROBLEM DESCRIPTION:
  The compiler produces an internal compiler error with -qipa and
  -g.
  In the internal options passed to xlCcode, there are two
  internal flags, which tell
  xlCcode if debug ops are present and what format to use for the
  debugger. If there
  are debug ops present, one of these internal flags must be
  re-set for each time the backend is called.
  If not in the case of TPO sending multiple partitions to the
  backend, the buffer can overflow by continuing
  to accumulate debug ops between partitions.
  

Problem conclusion

• The fix for this is to have TPO reset the internal flags for
  each partition when importing
  intermediate files with debug ops into each parition.
  

Temporary fix
