[emacs]

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 bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (hppa2.0w-hp-hpux11.00, X toolkit)
 of 2002-03-19 on schelde
configured using `configure  --prefix=/freeware/emacs 
--exec-prefix=/freeware/emacs/hppa --with-x-toolkit=athena 
--x-libraries=/usr/contrib/X11R6/lib'
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: nil
  locale-coding-system: nil
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

If visible-bell is set to t, emacs freezes completely when the bell is
invoked, for instance when typing C-g

This happens only on hp, using X and only for 21.2. No problems
encountered for 21.1 on hp, nor for 21.2 on hp without X, nor for 21.2
on SGI, linux-i386, alpha, solaris or ultrix with X.
