I realized that this is caused by `make-frame-invisible' that runs
when there is only one Emacs frame. At least for Cygwin, you should
be able to reproduce it in this way:
emacs -Q --eval '(make-frame-invisible (selected-frame) t)'
I also guess that it was harmless until about a week ago.
Why such an odd thing was run is because I was using this advice
to make `raise-frame' work on Cygwin.
(defadvice raise-frame (before make-it-work (&optional frame) activate)
"Make it work on Cygwin."
(make-frame-invisible frame t))
As I wrote in <http://thread.gmane.org/gmane.emacs.devel/150533>,
`raise-frame' doesn't raise iconified, invisible, or hidden frame.
Now I changed it into:
(defadvice raise-frame (before make-it-work (&optional frame) activate)
"Make it work on Cygwin."
(or (eq frame (selected-frame))
(make-frame-invisible frame)))
Even if Emacs should not crash for any Lisp code, it's a trivial
one among many(?) issues concerning Cygwin. So, I'm closing this
bug. Sorry for the noise.
