--- Comment #1 from janus at gcc dot gnu.org ---
Confirmed. There is some strange interaction with BIND(C). Reduced test case:


module base_mod

  implicit none

  type outer
  contains
    procedure, nopass :: mv_to_base
  end type

contains

  subroutine mv_to_base
  end subroutine

  subroutine foobar
    type(outer) :: a
    integer :: info

    interface 
      integer function try() bind(c)
      end function
    end interface

    call a%mv_to_base()
    info = try()
  end subroutine

end module
