23.0.60; unexpected horizontal frame size changes between buffers

[Sebastian Luque]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


With the latest emacs-snapshot package below:

emacs -q

eval this:

---<---------------cut here---------------start-------------->---
(require 'tex-site)
(add-hook 'LaTeX-mode-hook (lambda ()
                             (turn-on-reftex)
                             (LaTeX-math-mode)
                             (outline-minor-mode 1)))
---<---------------cut here---------------end---------------->---

Now do:

C-x C-f test.tex RET

Note the crazy change in horizontal frame size.  If you switch between
this and other buffers, things crazier because horizontal frame size
keeps shrinking.

If `(outline-minor-mode 1' is removed, then horizontal frame size stays
sane.  I isolated the problem with outline-minor-mode, but it also
occurs in other modes that insert menu items.



If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.60/etc/DEBUG for instructions.
