--- Comment #2 from janus at gcc dot gnu.org ---
This slightly reduced test case only needs a sinlge type and a one-dimensional
array:

  type :: child
  end type
  class(child), allocatable :: foo(:)
  allocate(foo(1))
  select type(foo)
    class is (child)
      call gfortran7_ICE(foo(1:1))
  end select
contains
  subroutine gfortran7_ICE(bar)
    class(child) bar(:)
  end subroutine
end
