Hi,
Recently Emacs on Cygwin crashes pretty often when I try to reply
to a mail in a new frame[1] using Gnus. I feel the frequency gets
high if a mail cites Japanese and Chinese mixture text (so, it's
due to decoding of characters?). But it hardly crashes if I have
a new empty message frame in advance besides the summary frame.
It happened too also when I used the LUCID toolkit last week.
I don't know what's wrong, sorry, but a gdb backtrace is attached.
Thanks.
[1] I use:
http://www.jpl.org/ftp/pub/elisp/message-multiple-frames.el.gz
It pops up a message frame after composing it.

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.
