[Message part 1 (text/plain, inline)]

1. Load the attached bigbug.el

2. open it in emacs and edit the definition of
   clang-project-default-settings, for example, remove "-v"

3. C-M-x the defcustom

4. C-h v clang-project-default-settings to show:

,----
| clang-project-default-settings is a variable defined in `bigbug.el'.
| Its value is (("SDKROOT" . "iphoneos")
|  ("OTHER_CFLAGS" "-ferror-limit=0" "-ObjC" "-DDEBUG=1" "-v"))
| 
| Original value was 
| (("SDKROOT" . "iphoneos")
|  ("OTHER_CFLAGS" "-ferror-limit=0" "-ObjC" "-DDEBUG=1"))
| 
| 
| Documentation:
| FIXME
| 
| You can customize this variable.
`----

i.e. C-M-x doesn't change the value of clang-project-default-settings,
this is opposite to the behaviour when lexical-binding is nil or in
previous emacsen.

I can't reproduce it here.
I did "src/emacs -Q -l ~/tmp/bigbug.el ~/tmp/bigbug.el"
then removed the "-v" and did C-M-x and then C-h v and it showed the
value did not have "-v" any more (and the original value was not
displayed because it's equal to the current value).

Can you try and figure out what's the difference between me test case
and your test case, to see what triggers the problem?

I built bzr trunk and this bug doesn't happen there.

I could only reproduce it with 24.2 from the emacs-24 branch
(2012-09-29).
