I confirmed it has been fixed on:

In GNU Emacs 24.3.50.1 (i686-pc-cygwin, X toolkit, Xaw3d scroll bars)
 of 2013-02-26 on yamaoka-PC
Bzr revision: 111882 eggert <at> cs.ucla.edu-20130226030908-c65ivknn1bm5hjru
Windowing system distributor `The Cygwin/X Project', version 11.0.11302000

Sorry for the noise.

Recently turn-on-font-lock set to some hook turns font-lock
on but turns it off immediately regardless of the value of
global-font-lock-mode.  Here's a recipe:

emacs -Q
Eval: (add-hook 'emacs-lisp-mode-hook 'turn-on-font-lock)
and visit some .el file.

In Emacs 24.2, it works no matter what global-font-lock-mode is.
Thanks.
