I couldn't use an unlimited pointer "class(*), pointer" inside a procedure. here I've got a simple module that has a base data type named "ex1" and a child type "ex2" that extends "ex1". ================================================================ module oop2 implicit none private type ex1 integer :: a end type ex1 type, extends(ex1) :: ex2 real*8 :: b end type ex2 public :: ex1, ex2, printit contains subroutine printit(ex) implicit none class(ex1), target, intent(in) :: ex ! local vars class(*), pointer :: pnt => null() pnt => ex ! buggy :( end subroutine printit end module oop2 ================================================================ The problem arises inside "printit" procedure. When I defined the unlimited pointer "class(*), pointer :: pnt" it cause no problem and code compiles fine with gfortran 4.8.1. However when I start pointing to the subroutine's dummy argument "ex" I get the following error: ================================================================ new_bug.f90:31:0: internal compiler error: Segmentation fault end module oop2 ^ Please submit a full bug report, with preprocessed source if appropriate. See <http://bugs.opensuse.org/> for instructions. ================================================================ This code compiles fine with ifort. Here is the main program that I used ================================================================ program test use oop2 implicit none type(ex1) :: b b%a = 2 call printit(b) ! done here end program test ================================================================ The intel compiler also works fine with polymorphic data when I use different type for variable "b" defined in the main program like "type(ex2) :: b". Thanks
