Message-ID: <1A1E0F9F3213446F8470BCDD907F82DD@us.oracle.com> (raw)
I do not have a recipe from emacs -Q, but this backtrace should help:
Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)

(if (get-text-property (point) (quote invisible)) (goto-char

prop buffer-invisibility-spec)))))) (skip-chars-forward "^\n") (if
(get-text-property (point) (quote invisible)) (goto-char

(= (point) end)) (and kill-whole-line (bolp))) (forward-visible-line 1)
(goto-char end)))
(if arg (forward-visible-line (prefix-numeric-value arg)) (if (eobp) (signal
(quote end-of-buffer) nil)) (let ((end (save-excursion (end-of-visible-line)
(point)))) (if (or (save-excursion (unless show-trailing-whitespace
(skip-chars-forward " " end)) (= (point) end)) (and kill-whole-line (bolp)))
(forward-visible-line 1) (goto-char end))))
(progn (if arg (forward-visible-line (prefix-numeric-value arg)) (if (eobp)
(signal (quote end-of-buffer) nil)) (let ((end (save-excursion
(end-of-visible-line) (point)))) (if (or (save-excursion (unless
show-trailing-whitespace (skip-chars-forward " " end)) (= (point) end)) (and
kill-whole-line (bolp))) (forward-visible-line 1) (goto-char end)))) (point))
(kill-region (point) (progn (if arg (forward-visible-line
(prefix-numeric-value arg)) (if (eobp) (signal (quote end-of-buffer) nil)) (let
((end (save-excursion (end-of-visible-line) (point)))) (if (or (save-excursion
(unless show-trailing-whitespace ...) (= ... end)) (and kill-whole-line (bolp)))
(forward-visible-line 1) (goto-char end)))) (point)))
kill-line(nil)
apply(kill-line nil)
...
The problematic code seems to be this part of `end-of-visible-line',
near the end:
(if (get-text-property (point) 'invisible)
(goto-char (next-single-property-change (point) 'invisible))
(goto-char (next-overlay-change (point))))
In the case at hand, `point' has an `invisible' property, but
`next-single-property-change' returns nil, which makes `goto-char' barf.
