Pre-processed source file

I'm getting an ICE compiling a Fortran file. I'll attach a stripped down
reproducer that demonstrates the problem (the real file is 3000+ lines and
requires many, many external modules and libraries).

Per instructions, running gfortran on our .F90:

--- Comment #5 from Matt Thompson <matthew.thompson at nasa dot gov> ---
An additional thought. You have a reduced test case which dies in Comment #3
(which fails for gfortran 4.9). However, you can make something similar which
succeeds:
****
program main

implicit none

type :: MAPL_LocStream
  type(MAPL_LocStreamType), pointer :: Ptr
end type

type MAPL_Tiling
   integer :: IM
end type

type MAPL_LocStreamType
   type(MAPL_Tiling), pointer  :: Tiling(:)
end type

contains

  subroutine MAPL_LocStreamGet (GRIDIM)
    type(MAPL_LocStream) :: LocStream
    integer, pointer     :: GRIDIM(:)

    integer, pointer     :: LP(:)

    LP => LocStream%Ptr%Tiling(:)%IM

  end subroutine

end program main
****

So, it's not that gfortran/gcc can't do the pointer, it's that it can't do it
to a pointer passed through the interface. Note that this still fails:

****
program main

implicit none

type :: MAPL_LocStream
  type(MAPL_LocStreamType), pointer :: Ptr
end type

type MAPL_Tiling
   integer :: IM
end type

type MAPL_LocStreamType
   type(MAPL_Tiling), pointer  :: Tiling(:)
end type

contains

  subroutine MAPL_LocStreamGet (GRIDIM)
    type(MAPL_LocStream) :: LocStream
    integer, pointer     :: GRIDIM(:)

    integer, pointer     :: LP(:)

    LP => LocStream%Ptr%Tiling(:)%IM
    GRIDIM => LP

  end subroutine

end program main
