wrong-type-argument number-or-marker-p nil in lentic-chunk-comment-buffer #53

Open kevinboulain opened 5 years ago

Here is another bug that I accidentally encounter when I don't pay much attention while editing some files. I used the same setup as in #52, but with the patch to avoid the crash on M-c.

I added to the beginning of config.el:

(setq load-prefer-newer t) ; to be sure I pick the local patch
(setq debug-on-error t) ; to get the following traceback

Create and open crash.org:

cat > /tmp/trash/crash.org  << EOF
#+begin_src emacs-lisp
#+begin_src emacs-lisp
#+begin_src emacs-lisp
EOF

emacs -Q -l /tmp/trash/config.el /tmp/trash/crash.org

Validate the local variables with !. Then C-c , c & C-c , t.

Finally, update crash.org to reflect the following (add #+end_src between the second and third #+begin_src emacs-lisp):

#+begin_src emacs-lisp
#+begin_src emacs-lisp
#+end_src
#+begin_src emacs-lisp

Then lentic will crash with (sorry for the wall of text):
