emacs crashing on when writing text in telugu-itrans (infact with any
Indian script input method) while auto-complete-mode[1] enabled.
I can reproduce this on my ubuntu 11.10 and 10.04.
here is how one can reproduce.
----------------------------------------------------
emacs -Q ; start emacs with out any customizations
M-x load-file popup.el ; file attached to this mail
M-x load-file auto-complete.el ; file attached to this mail
M-x switch-to-buffer *scratch* RET
M-x auto-complete-mode ; enable auto-complete-mode
C-\ telugu-itrans RET ; change input method to telugu
; lets type any word twice for eg: nuvvu nuvvu
nuvvu nuvvu
----------------------------------------------------
now emacs crashes

Sorry; I saw auto-complete mentioned and assumed this was a dupe of
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10159
But it probably was not? If so, I will unmerge and reopen 10159.

It could be. But then it could be not: the crash in 10159 is in a
different place and is not reproducible. We can only deduce it's a
duplicate if the OP will report that it no longer crashes for them.

@Eli
I am the reporter of this bug. if you are referring me as OP here,
I already sent an email confirming that this bug is fixed. But some how
that mail didn't show up in the list.

Your mail did show up, but I was not talking about this bug (#10263),
I was talking about bug #10159, which AFAIK was filed by someone
else. Glenn was wondering whether 10159 was the same bug, and is
therefore also fixed. We'd need confirmation from Alex Murray about
that.

Sadly I have been unable to reproduce this bug [#10159] since
recompiling Emacs with no optimisations - however, I will certainly try
to keep reproducing it - I am not so sure the fix in
revision 106658 will fix this bug [#10159] since the crash is not at the
same location, but I will also try and see if I can reproduce the crash
with the latest trunk too.

Okay I seem to be able to reproduce this fairly easily with the
following init.el settings and the recipe below:
;; install auto-complete from melpa since is pretty much the
;; latest development version
(require 'package)
(add-to-list 'package-archives
'("melpa" . "http://melpa.milkbox.net/packages/") t)
(package-initialize)
(package-install 'auto-complete)
;; auto-complete
(require 'auto-complete-config)
(ac-config-default)
(setq ac-auto-start 1) ; autostart with a single character
(setq ac-auto-show-menu ac-delay)) ; show menu autoomatically
;; quick help has to be after menu so again set to 10ms more
(setq ac-quick-help-delay (+ ac-auto-show-menu 0.01))
---------------------------------------------------
With the above init.el launch emacs and then switch to the scratch
buffer. Now type anything to get auto-complete to show up completions -
say just a single letter such as d - and then hit space very quickly
after that - it may take a bunch of tries to get it to crash but
eventually it seems that if you hit space just after auto-complete has
popped up the menu (and by just after I am talking fractions of a
second) emacs can crash. I think hitting space causes auto-complete to
hide the popup menu and then in redrawing the display emacs now
crashes...
