Another related test case was recently reported by Andrew Benson at
http://gcc.gnu.org/ml/fortran/2011-02/msg00111.html:


module mod1
  type treeNode
  end type treeNode
contains
  subroutine proc1(thisNode)
    class (treeNode), target, intent(in) :: thisNode
    select type (thisNode)
    type is (treeNode)
       workNode => thisNode
    end select
  end subroutine proc1
end module mod1


workNode => thisNode
       1
Error: Non-POINTER in pointer association context (pointer assignment) at (1)
