Subject: 24.0.50; `customize-rogue' error: Symbol's value as variable is void
Date: Thu, 22 Jul 2010 15:28:56 -0700

emacs -Q
 
Eval this:
 
(defcustom foo 'start
  ""
  :type '(choice  (const start) (const end))
  :group 'foobar)
 
M-x customize-option foo
 
1. Use the Value Menu to change the value to `end'.
2. Use the State menu to `Set for current session' (value is `end').
3. Use the State menu to `Set to Backup Value' (value is `start').
4. M-x customize-rogue
 
This error message appears:
 
"Symbol's value as variable is void: start"
 
The problem is the call to `eval' here:
 
(when (and cval ;Declared with defcustom.
           (default-boundp symbol) ;Has a value.
           (not (equal (eval (car cval)) ; <==============
                       ;; Which does not match customize.
                       (default-value symbol))))
  (push (list symbol 'custom-variable) found))
 
The sexp that is the arg to `eval' is `(start)'.
