Error description

  • The compiler is encountering an internal compiler error when
    processing pointers to functions.
    
    
       ===== TEST CASE =====
    
    module mm
      CONTAINS
    
      function f1()
        integer, pointer :: f1
        integer, target :: a1
        f1 => a1
      end function
    
      subroutine s2()
        call s1(f1())
      end subroutine
    
      subroutine s1(a3)
        integer, pointer :: a3
      end subroutine
    
    end module
    
    
    
    $ xlf -q64 -O2 -c reduce.F90
    ** mm   === End of Compilation 1 ===
    1585-100  Internal compiler error -- please contact your service

    1501-511  Compilation failed for file reduce.F90.
    

Local fix

  • Reorder procedure definitions so that the function returning
    pointer results is defined after the first procedure definition
    that calls it.
    

Problem summary

  • PROBLEM DESCRIPTION:
    The compiler encounters an internal compiler error when -O2 or
    higher optimization is included in the invocation.
    
    USERS AFFECTED:
    Applications that pass a pointer function result to a procedure
    and the function definition appears before the call-site.
    

Problem conclusion

  • The problem has been fixed.
    

Temporary fix
