[gnu.emacs.bug] fatal window bug

gildea@BBN.COM (Stephen Gildea) (02/15/89)

The following sequence of keystrokes will cause Emacs 18.52 to abort
and dump core.  Don't try this with unsaved buffers!

Start a fresh Emacs:
emacs -q

And type into the *scratch* buffer:
(setq badw (selected-window)) LFD
C-x 2
C-x 0
(select-window badw) LFD
C-x 2
C-x 0

You get: "Fatal error (4)."
