Hello,

this is another problem with rev. 117587. Starting from this revision
(including rev. 117605) emacs compiled with X support segfaults when I
run auto-complete[1] tests.

Revision 117586 with X support and emacs of revision 117605 compiled
without X support work fine. I attached output of gdb for all three
cases.

Some information about my system:
OS:           Archlinux x86_64
Compiler:     gcc (GCC) 4.9.1
gtk3:         3.12.2
xorg-server:  1.16.0
intel-video:  2.99.914
tmux:         1.9a_122_gf8481f9
rxvt-unicode: 9.20

Configuration options with X support:

  --prefix=/usr
  --sysconfdir=/etc
  --localstatedir=/var
  --libexecdir=/usr/lib
  --with-xpm
  --with-jpeg
  --with-tiff
  --with-gif
  --with-png
  --with-rsvg
  --with-x-toolkit=gtk3
  --with-xft
  --with-libotf
  --with-dbus
  --with-gsettings
  --without-sound

Configuration options without X support:

  --prefix=/usr
  --sysconfdir=/etc
  --localstatedir=/var
  --libexecdir=/usr/lib
  --with-dbus
  --without-x
  --with-gsettings
  --without-sound
