Related test case by Mikael, resulting in a segfault (PR 46196 comment #11):

      module type_a
      type a
              sequence
      end type a
      end module type_a

      module type_a_bis
      type a
              sequence
      end type a
      end module type_a_bis

      use type_a
      use type_a_bis, only: b => a

      type(b) :: y
      call bar(y)

    contains

      subroutine bar (x)
        type(a) :: x
      end subroutine bar

  end
