Message-ID: <CAFyQvY1CoaOXCnfpZ7h7PeKsh-kQHBgMya1Gce9f=w9kd+fEBQ@mail.gmail.com> (raw)
In-Reply-To: <CAFyQvY3JBuerkxH+41KkObn3myf11qhPO9UMk28SLZiYJNuG0A@mail.gmail.com>

I put some debug statements in the fci-redraw-frame () function in
fill-column-indicator:

(defun fci-redraw-frame ()
  "Redraw the fill-column rule in all windows on the selected frame."
  (let* ((wins (window-list (selected-frame) 'no-minibuf))
         (bufs (delete-dups (mapcar #'window-buffer wins))))
    (message "Buffer list: %s" bufs)
    (dolist (buf bufs)
      (with-current-buffer buf
        (when fci-mode
          (message "In buffer %s" buf)
          (fci-delete-unneeded)
          (fci-update-all-windows))))))

After that,
(1) I had the frame with 2 windows.
(2) I had fill-column-indicator.el in one window, and
(3) did M-: (eww "http://www.braveclojure.com/basic-emacs") with point
in the other window.

Emacs of course went into infloop but I was able to get out of it with
C-g, and saw these messages in *Messages* buffer:

There were many more of such messages

Does the fci-redraw-frame definition above and the fact that it is
added to window-configuration-change-hook give an idea as to what's
causing this infloop?
