Apparently an ICE also occurs if the argument intent is removed but "type" is
replaced by "class."  See below.  Is this fixed by the patch in comment 3?

$ cat ice_on_class_dummy_with_unlimited.f90 
  implicit none
  type foo
    class(*), allocatable :: bar
  end type
contains
  integer function foobar(this)
    class(foo) :: this
  end function
end
