PrettyPix.f95:
======================
module PrettyPix_module
implicit none
type Spline
real, allocatable, dimension(:) ::y2
end type Spline
type Path
type(Spline) :: r(3)
end type Path
type Scene
type(path) :: look_at_path
end type Scene
contains
subroutine scene_set_look_at_path(this,p)
type(scene), intent(inout) :: this
type(path), intent(in) :: p
this%look_at_path = p
end subroutine scene_set_look_at_path
end module PrettyPix_module
===================
The problem seems to disappear if r(3) -> r

------- Comment #2 from pault at gcc dot gnu dot org 2008-11-22 09:09 -------
Oddly,
type Path
type(Spline), allocatable :: r(:)
end type Path
compiles OK:-)
Given that the ICE is caused by
gcc_assert (GFC_DESCRIPTOR_TYPE_P (type))
it must be that the type(Spline) :: r(3), which is definitely not a descriptor
type, is incorrectly being treated as if it is. The allocatable component code
in trans-array.c is meant to handle this, so there is a coding error somewhere.
I'm on to it:-)

Provisional fix for PR
This is half way through regtesting - have to go to a movie, so will see
