Well, is there anything better that could be done about it? I don't
think so. Finish is going to take you back to whatever GDB thinks the
previous frame is.
Now, of course, GDB shouldn't get confused in the first place. That's
always worth filing a bug about, although it may be a case of
inadequate debug information or other similar problems out of our
control.
