Subject: bug#20705: Emacs segfaults when typing "(yas-expand" after M-: in yas-minor-mode
Date: Sun, 31 May 2015 13:44:43 -0700 [thread overview]
Message-ID: <556B72BB.4080508@live.com> (raw)
Hi all,
I'm running 25.0. I've just run into a strange segfault which kicks in when I run M-x yas-minor-mode followed by M-: (yas-expand. The following is a recipe to reproduce it with the latest source:
rm -rf temp-emacs-profile
emacs -Q \
--eval '(setq user-emacs-directory "temp-emacs-profile")' \
-l package \
--eval "(add-to-list 'package-archives '(\"melpa\" . \"http://melpa.org/packages/\") t)" \
--eval "(package-refresh-contents)" \
--eval "(package-initialize)" \
--eval "(package-install 'yasnippet)" \
--eval "(yas-minor-mode)"
Then type `M-: (yas-expand'. Emacs segfaults after the last 'd' is typed. Surprisingly, the problem does not appear if one uses the yasnippet verson from ELPA, only the more recent one from MELPA.
GDB says
Program received signal SIGSEGV, Segmentation fault.
