Below is a reproducible bug coming from the xassert at xdisp.c:5268.
I did some debugging on it and found that the charpos and bytepos in
it.current.pos really fail to correspond. They were taken from
row->end from init_to_row_end called from try_window_id.
I think the cause of this bug is that inserting the multibyte
character u-umlaut at vpos 1 fails to properly update the row->end
at vpos 3.

Subject: Emacs crashes while composing mail
Sender: address@hidden

Hi
This is the strangest Error I've ever seen. Emacs crashes consistently
while composing mail and using the iso-accents-mode.
I was able to reduce my .emacs to the following
==== .emacs ====
(custom-set-variables
'(global-font-lock-mode t nil (font-lock))
'(mail-archive-file-name "~/mail/sent")
)
================
Then I do the following steps:
M-x mail (opens *mail* buffer)
M-x iso-accents-mode
Go to the subject: line and enter ["u] (without the brackets, creates a u
Umlaut)
Go to line after [--text follows this line--]
Enter [S-h] (an upcase H)
Emacs crashes without any further notice!!!
Since I often write emails with umlauts in the subject, I would be
very glad if somebody could figure out, what causes this crash. I
would be glad to assist, if I get further instructions.
Thanks a lot!
Martin
