Subject: bug#10263: 24.0.92; emacs crash with auto-complete plugin
Date: Sat, 10 Dec 2011 10:40:23 +0000 [thread overview]
Message-ID: <SNT125-W356C2049782576CC0AA6F0CCBE0@phx.gbl> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 801 bytes --]
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
