Emacs hangs when "foo\\|\\|bar" is in `font-lock-keywords' |
Date: |
Sun, 26 Jun 2005 22:54:51 +0200 |
User-agent: |
Gnus/5.11 (Gnus v5.11) Emacs/22.0.50 (gnu/linux) |
Steps to reproduce:
C-u 1 M-x font-lock-mode RET
M-: (add-to-list 'font-lock-keywords "foo\\|\\|bar") RET
M-x font-lock-fontify-buffer RET
This causes Emacs to hang in a busy loop.
In GNU Emacs 22.0.50.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
