Sorry for the long subject line, but I'm unsure if this is one bug
or two. I've written an extensive post describing various test cases
and outcomes on my blog
(http://hholz.com/blog/2012/diagnosing-an-emacs-bug/).
I've listed the minimal case to reproduce the bug(s?) in this
bug report.

Starting with an empty .emacs file

1. M-x customize-apropos<RET>shell-switcher
2. set shell-switcher-new-shell-function to shell-switcher-make-shell
   set shell-switcher-mode to on
   click on Apply and Save

   the above steps create a .emacs containing exactly

   (custom-set-variables
    ;; custom-set-variables was added by Custom.
    ;; If you edit it by hand, you could mess it up, so be careful.
    ;; Your init file should contain only one such instance.
    ;; If there is more than one, they won't work right.
    '(shell-switcher-mode t)
    '(shell-switcher-new-shell-function (quote shell-switcher-make-shell))
    )

   (custom-set-faces
    ;; custom-set-faces was added by Custom.
    ;; If you edit it by hand, you could mess it up, so be careful.
    ;; Your init file should contain only one such instance.
    ;; If there is more than one, they won't work right.
    )

3. quit emacs. launch emacs (/Applications/Emacs.app/Contents/MacOS/Emacs)
4. M-x shell-switcher-new-shell (launches buffer in eshell)
5. M-x customize-apropos<RET>shell-switcher (flags both settings
   CHANGED outside Customize)
6. C-x C-f ~/.emacs (contents of .emacs is unchanged)

bug#12582: 24.1.50; customize settings not persisting across sessions + CHANGED outside Customize flag issue

There is no "shell-switcher" in Emacs.
Most probably, this is a bug in whatever package provides that feature,
and should be reported to whoever maintains it.

This is a rather old version of the Emacs trunk.

I downloaded the latest https://github.com/DamienCassou/shell-switcher
and it works fine for me with both Emacs 24.2 and the current trunk.

I would have done that if the problem had been local to the package. However, there remains the issue with CHANGED outside Customize. 

My decision to report it to emacs was very much shaped by http://stackoverflow.com/questions/10042639/what-does-saved-and-set-mismatch-and-in-particular-the-mismatch-part-me. In that q/a, the same flag was identified as being problematic, part of a two bug interaction that is rather reminiscent of this one.

In any case, I have long since found a workaround. The extra work diagnosing and reporting it was purely a community contribution. I can only hope someone finds it useful.

ROFL! Take it up with the homebrew folks, it's their build.

The problem is local to the package if it only occurs with variables
from that package. Can you demonstrate this problem with any standard
Emacs custom option?

It's trivial to make such a bug occur. Eg:

(defvar shell-switcher-new-shell-function 57)

(defcustom shell-switcher-new-shell-function 'shell-switcher-make-eshell
  "..."
  :group 'shell-switcher)

Evaluating that will give a "CHANGED outside Customize." message.

OK, that's an artificial example, but similar things can easily happen
for example with packages split into multiple source files that
accidentally define variables more than once. It's a bug in the package,
not in Custom.

Shell-switcher is not part of Emacs, so "empty .emacs" doesn't sound
quite right.  I suspect the problem is somewhere in the local
modifications you have.

Of course, it can still be due to a bug in Emacs's Customize code, but
we'd need some recipe starting from a really empty local customization
(which would hence explicitly load shell-switcher.el).

Cool. That's useful info. 

How do I tell the init process to source from github rather than one of the repos? A pointer to the relevant section of the manual (or the relevant manual) would be deeply appreciated. Downloading manually isn't scalable :(

That was one of my realizations in this process; that I've hit the point at which I need to get up to speed on BDD for emacs.

That way I could spawn a pristine copy to start with, not to mention have emacs to keep notes with while working on the problem.

Any favorite references for getting up to speed in the area? I'm fluent in BDD in other platforms.

Ooo… Thanks, your example is very helpful.

Is there a way to have the init process source shell-switcher from github rather
than a repo? Downloading it manually isn't scalable :(

I'm closing this because I do not think there is an Emacs bug here.
Please feel free to send more info if you think there is.
We would need a recipe starting from an empty .emacs file that
shows how to reproduce the problem.
