output_set_got in i386.c has

#ifdef DWARF2_UNWIND_INFO
      /* Ensure all queued register saves are flushed before the
         call.  */
      if (dwarf2out_do_frame ())
        {
          rtx insn;
          start_sequence ();
          insn = emit_barrier ();
          end_sequence ();
          dwarf2out_frame_debug (insn, false);
        }
#endif

We inserted an instruction. But we are using the
old barrier_args_size.  It looks wrong to me.
