Another one, with mutually recursive types

  module type_a_b
      type a
              sequence
              type(b), pointer :: pb
      end type a
      type b
              sequence
              type(a), pointer :: pa
      end type b
  end module type_a_b

  module type_a_b_bis
      type a
              sequence
              type(b), pointer :: pb
      end type a
      type b
              sequence
              type(a), pointer :: pa
      end type b
  end module type_a_b_bis

      use type_a_b, only: a1 => a, b1 => b
      use type_a_b_bis, only: a2 => a, b2 => b

      type(a2) :: y
      call foo(y)

    contains

      subroutine foo(x)
        type(a1) :: x
      end subroutine foo
  end

Infinite loop at compile time. I couldn't think of a sane person writing such
code anyway.
