IV30040: INTERNAL COMPILER ERROR AT -O2 IN XLFENTRY

November 2012 PTF for XL Fortran for AIX, V14.1
March 2013 PTF for XL Fortran for AIX, V14.1

APAR status

• Closed as program error.

Error description

• Compiling the test case with -O2 fails with the following error
  message:
  
  
  /sw/ibm/xlf/14.1.0/usr/bin/xlfentry
  
      1517-009: (U) Error in compiler runtime system; compilation
  ended.
  rm /tmp/F818284674f-aiid
  
  /sw/ibm/xlf/14.1.0.1/usr/bin/.orig/xlf2003_r: 1501-230 (S)
  Internal
  compiler error; please contact your Service Representative. For

Local fix

• Remove -O2 or use -qnoopt
  

Problem summary

• USERS AFFECTED:
  Users of XL Fortran who have large applications and recursive
  derived types are potentially affected by this issue.
  
  PROBLEM DESCRIPTION:
  Large applications with many derived types that are very deep
  and recursive take a long time to
  compile, require a lot of /tmp space, and sometimes causes an
  abend in the compiler.
  

Problem conclusion

• The problem has been fixed by changing the logic of some
  internal functions to handle type recursion.
  

Temporary fix
