bug#10159: auto-complete causes crash in emacs HEAD

I'm one of the auto-complete maintainers. AC is a really popular
package, and for me at least, this bug makes Emacs near-unusable.
Fixing this bug is my top priority as far as FOSS stuff goes, so any
help from those who know the C source would be appreciated.

I can reproduce this pretty much every time with optimizations
disabled, using the attached init-ac.el. Before running this test,
make sure you have auto-complete installed: execute

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "http://melpa.milkbox.net/packages/") t)
(package-initialize)

and then M-x package-install auto-complete.

Now, exit that emacs, and use gdb -ex run --args emacs -Q --load
init-ac.el and type "def " as fast as you can. It should crash with
SIGSEGV.

Starting program: /usr/local/bin/emacs -Q --load init-ac.el

Attached is the result of bt full in gdb.txt. I left GDB open in case
I should run some more commands.

And here is output from report-emacs-bug:
