Bus error on x-close-connection

[Otto Maddox]

Start Emacs on the local X display:

$ emacs -Q &

Open an ssh-forwarded X connection in another xterm:

$ ssh -X localhost
$ echo $DISPLAY
localhost:10.0

Do this in Emacs:

(make-frame-on-display "localhost:10.0")

C-x 5 0 on the new frame

(x-display-list)
=> (":0.0" "localhost:10.0")

(x-close-connection "localhost:10.0")
=> nil

(x-close-connection "localhost:10.0")   ; yes, do it twice

and then Emacs crashes with a bus error.
