This is a report I also sent to cl-xmpp-devel as that is where I
discovered it.  It does however seem to be more related to Flexi-Streams
on ACL8.1.

Thanks in advance for any ideas you might have about how to resolve this
issue.

Hi I know this is a small list and that this problem is likely not to do
specifically with CL-XMPP code, but with one of the libraries it uses.
So if you can help by even suggesting where better I might ask this, it
would be appreciated.  Thank you.

What follows is run using the latest cl-xmpp and cxml/closure-commons
from CVS along with other libraries from asdf-install tarballs.  I use
ACL8.1 on linux-x86.32.  The net result is that the lisp crashes and
dies with a segmentation violation.  Obviously that in itself is a Franz
issue, but this happens because (figure-encoding...) calls (read-byte
...) on a flexi-stream.  And I figure this doesn't make much sense.

I've traced figure-encoding to see that this is clear.  Perhaps there
should be a specialized method of figure-encoding for flexi-streams?

Again, if you can help me to direct this query to a better place, please
let me know.

Best,
- -Jason
