I observe hangs when using sh-mode in recent trunk emacs (latest commit
Tue Nov 5 18:36:37 2013 +0200). Recipe to reproduce:
- emacs -Q
- C-x C-f foo.sh
- type “for i in”
- immediately after entering the ‘n’, emacs will hang
Setting debug-on-quit to t and quitting yields the following backtrace:
Debugger entered--Lisp error: (quit)
re-search-backward("\\(?:\\(?:^\\|[^\\]\\)\\(?:\\\\\\\\\\)*\\(\\(?:&&\\|;\\(?:;&\\|[&;]\\)\\||[&|]\\|[&;|]\\)\\)\\)\\="
1 t)
looking-back("\\(?:^\\|[^\\]\\)\\(?:\\\\\\\\\\)*\\(\\(?:&&\\|;\\(?:;&\\|[&;]\\)\\||[&|]\\|[&;|]\\)\\)"
