Subject: edebug can hang Emacs
Sender: emacs-pretest-bug-bounces+rms=gnu.org@gnu.org
This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.
Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.
In GNU Emacs 21.2.92.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
of 2002-11-22 on confusibombus
Important settings:
value of $LC_ALL: nil
value of $LC_COLLATE: nil
value of $LC_CTYPE: nil
value of $LC_MESSAGES: nil
value of $LC_MONETARY: nil
value of $LC_NUMERIC: nil
value of $LC_TIME: nil
value of $LANG: C
locale-coding-system: nil
default-enable-multibyte-characters: t
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
In emacs -q, edebug the following defun using C-u M-C-x:
(defun test ()
(let ((l (make-list 100000 1)))
(dolist (i l)
(1+ i))))
Now call it:
(test)
When you get to the dolist, Emacs hangs. I cannot awaken it using C-g
multiple times, ESC multiple times, C-z multiple times, having the
window manager send a kill, switching to the xterm running GDB and
hitting C-c or C-z multiple times also does not change anything --
neither Emacs nor GDB is killed or interrupted.
This should be handler more gracefully. I don't even know what causes
the problem -- is Emacs trying to print the list l in a message, and
trying to determine which parts not to show? If so, perhaps Emacs
needs a way to estimate the size of something, before starting to
print it.
Alex.
