Hello,

With Emacs 25.0.92, Emacs 25.0.93, and Emacs 25.1.50, Emacs start to
use 100% CPU.
That is, afetr I start Wanderlust(MUA) on Emacs, and try to open some
folders in it, Emacs starts to use 100% CPU, and unresposible.

I investigated the latest Emacs with git bisect.
As a result, I found that xftfont.c has got a bug as follows.

※ test = Start Emacs & Wanderlust, then try to open the folder in
Wanderlust. OK means "can open without any problem", NG means "Emacs
eat 100% CPU).
