bug#17257: 24.3.90; ediff causes "Wrong type argument: listp, [#<overlay


From: YAMAMOTO Mitsuharu
Subject: bug#17257: 24.3.90; ediff causes "Wrong type argument: listp, [#<overlay ...> ...]" error
Date: Sun, 13 Apr 2014 18:11:38 +0900
User-agent: Wanderlust/2.14.0 (Africa) SEMI/1.14.6 (Maruoka) FLIM/1.14.8 (Shij┼Ź) APEL/10.6 Emacs/22.3 (sparc-sun-solaris2.8) MULE/5.0 (SAKAKI)

Steps to reproduce:

  1. $ emacs -Q &
  2. M-x ediff RET SOME-FILE RET ANOTHER-FILE RET
     (The contents of SOME-FILE and ANOTHER-FILE should be different.)
  3. Type `n' several times.

Result:

  ediff-set-fine-diff-properties: Wrong type argument: listp, [#<overlay ...> 
...]

The error occured at line 825 in lisp/vc/ediff-diff.el:

   817  (defun ediff-set-fine-diff-properties-in-one-buffer (buf-type
   818                                                       n &optional 
default)
   819    (let ((fine-diff-vector  (ediff-get-fine-diff-vector n buf-type))
   820          (face (if default
   821                    'default
   822                  (ediff-get-symbol-from-alist
   823                   buf-type ediff-fine-diff-face-alist)
   824                  )))
   825      (dolist (overl fine-diff-vector)
   826        (ediff-set-overlay-face overl face))))

The value of `fine-diff-vector' was a vector of overlays, so dolist
couldn't be applied to it.
