This is 100% reproducible. It does not happen on 20.4.
System is mips-sgi-irix6.4. XEmacs 21.0-b54.
To reproduce:
1. xemacs -vanilla
2. Do a `narrow-to-region' in *scratch* from halfway in the first line
through the end of the buffer.
3. Do a `widen'. Notice that the beginning of the first line is not
redisplayed.
4. Hit C-l. Boom!
Are you sure the trace is from a vanilla XEmacs? The trace seems to
indicate that C-l is bound to `center-to-window-line', which should
not be the default.

Are you sure the trace is from a vanilla XEmacs? The trace seems to
indicate that C-l is bound to `center-to-window-line', which should
not be the default.
I can vouch for that. session log follows, Installation is attached:
summit$ uname -a
SunOS summit 5.5 Generic sun4m sparc SUNW,SPARCstation-5
summit$ xemacs -vanilla
Fatal error: assertion failed, file redisplay.c, line 6757, cur_elt >= 0
Fatal error (6).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
Please report this bug by running the send-pr script included
with XEmacs, or selecting `Send Bug Report' from the help menu.
As a last resort send ordinary email to `crashes(a)xemacs.org'.
*MAKE SURE* to include the information in the command
M-x describe-installation.
If at all possible, *please* try to obtain a C stack backtrace;
it will help us immensely in determining what went wrong.
To do this, locate the core file that was produced as a result
of this crash (it's usually called `core' and is located in the
directory in which you started the editor, or maybe in your home
directory), and type
gdb /usr2/paulk/bin/sparc-sun-solaris2.5-sparcworks/xemacs core
then type `where' when the debugger prompt comes up.
(If you don't have GDB on your system, you might have DBX,
or XDB, or SDB. A similar procedure should work for all of
these. Ask your system administrator if you need more help.)
Lisp backtrace follows:
center-to-window-line(nil nil)
# bind (window n)
recenter(nil)
# bind (command-debug-status)
call-interactively(recenter)
# (condition-case ... . error)
# (catch top-level ...)
Abort(coredump)
