Hi. I'm using a very recent emacs built from master:
eb3416016b4
I'm observing (comment-region) go into an infinite loop when presented
with particular data. I'm attaching a small source file that
demonstrates the issue. To see it break, run this:
emacs --eval '(add-hook (quote c-mode-common-hook) (lambda () (setq
comment-start "//" comment-end "")))' \
--eval '(global-set-key (kbd "<f5>") (lambda () (interactive)
(comment-region 16 45)))' \
-Q tst6.c
This loads the demo file with a clean configuration, and runs two bits
of lisp:
1. Sets up a c++ commenting style. This is required for the issue to
present itself
2. Binds f5 to run the problematic (comment-region)
On my machine, invoking emacs that way, and then hitting f5 shows the problem.
void f(void)
{
g( // output
s );
}
