[ESS] Emacs 24 + ESS + auto-complete-mode crashing on Ubuntu

[Christian Zang]

Dear list,

I have some serious issues with Emacs 24 crashing on Ubuntu 12.04 during ESS
sessions.  I use emacs-snapshot (currently version 24.2.50.1 from
ppa:cassou/emacs) and latest ESS from git (12.09, c3990d7859).
Everything works fine and as expected as long as I do not turn on
auto-complete-mode.  If auto-complete-mode is turned on, Emacs quickly
crashes in an unpredictable fashion in midst of auto completion.  As
all other things I use auto-completion for (python, org-mode,
latex...) work fine, I suspect ESS to be the culprit.

I use latest auto-complete-mode and popup.el from git, and also tried
several downgrades for Emacs, ESS, and auto-complete-mode without
success.

Is anyone experiencing the same problem? Any help appreciated, thanks!

Here is the minimal init.el that reproduces the crash:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;; popup

(add-to-list 'load-path "~/.emacs.d/elisp/popup/")
(require 'popup)

;;; auto-complete

(add-to-list 'load-path "~/.emacs.d/elisp/autocomplete/")
(require 'auto-complete)

;;; ESS

(add-to-list 'load-path "~/.emacs.d/elisp/ESS/")
(add-to-list 'load-path "~/.emacs.d/elisp/ESS/lisp/")
(add-to-list 'load-path "~/.emacs.d/elisp/ess-tracebug/")
(require 'ess-site)

;;; enable autocomplete in ESS mode

(add-hook 'ess-mode-hook 'auto-complete-mode)
(add-hook 'inferior-ess-mode-hook 'auto-complete-mode)
(setq ess-use-auto-complete t)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Kind regards,
Christian
