--- Comment #11 from Mikael Morin <mikael at gcc dot gnu.org> 2010-10-30 12:51:54 UTC ---
Another bug, we don't check that components are non-null before entering the
loop. 


      module type_a
      type a
              sequence
      end type a
      end module type_a

      module type_a_bis
      type a
              sequence
      end type a
      end module type_a_bis

      use type_a
      use type_a_bis, only: b => a

      type(b) :: y
      call bar(y)

    contains

      subroutine bar (x)
        type(a) :: x
      end subroutine bar

  end

PS: Dominique, you can start hacking with this testcase.
gfc_compare_derived_types is called with it (when comparing type of `y' vs type
of `x'). 

PS2: we will need a new PR in the end.
