[Bug: 21.4.19] Binary characters in buffer causes emacs to crash

Dear Bug Team!
XEmacs crashes when trying to view a buffer that contains some strange
binary (i.e. non-roman) characters in it.
It crashes and prints out the following message:
Fatal error: assertion failed, file /usr/src/xemacs-21.4.19/src/redisplay-msw.c, line 563, runs[i].dimension == 1
Aborted (core dumped)
I first saw this bug when I had received some SPAM email containing
Chinese or Japanese characters in it, and was reading the mail using
Gnus. It would cause Xemacs to crash when trying to display the
article summary buffer in Gnus (which I assume was trying to display
the Subject line).
When composing this bug report, I've discovered that it is not just a
problem in Gnus, but it will also cause xemacs to crash when simply
editing a buffer with those characters in it.
Below is a uuencoded example of a file that triggers the
bug. I had to uuencode it so it won't crash emacs when I
tried to insert it; uudecode it before testing.
To reproduce the bug, simply try to visit the file. It is
expected that xemacs will simply display the file in a
buffer, but it crashes instead.
Thanks.
