This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug. If you can, give
a recipe starting from `emacs -Q':
---
Error: "forward-list: Scan error: "Containing expression ends
prematurely", 336, 336"
How to reproduce it:
- emacs -Q
- switch to *scratch*
- in the following code:
(abc (def) (ghi) lmn)
`forward-list' fails in different positions, for instance (| is point):
(abc (|d|e|f|) (ghi) lmn)
Software: GNU Emacs 23.3.1 (i686-pc-linux-gnu, GTK+ Version 2.20.1) of
2011-12-10 on debian

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.

Hi all,
while I can easily reproduce this on current Emacs (25.1.50.1), I'm not
sure whether this is really a bug. (Maybe it is a bug in the
docstring?)
Best,

Can you propose a suitable change to the doc string? (We should
probably make similar changes in other related commands in lisp.el.)
Thanks.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
This has changed a bit since reported a decade ago. The command now says:
user-error: No next group
Which is the correct thing here -- the command is (now) documented to
"Move forward across one balanced group of parentheses.", and in the
case here, there's no group of parentheses to move forward over.
So this works as intended (`up-list' is the command to use in this
instance, most likely), and I'm closing this bug report.
