LYNX-DEV Fote's 14-Dec 2-6-mod crashes on ultrix too

[--- Alvian ---]

Hi Fote,

I wish to report this crash.  My system is DEC Ultrix.  
Lynx is built with slang.  This bug causes an unaligned 
access & bus error on ultrix.  Lynx exits with signal 10 
via interrupt 0.

Looks like your fix of <HR> isn't working so well. :-(

This html dies:
<h1>Hello</h1>
<hr>

This dies too:
Sample text<p>
<hr>

But this is ok:
Sample text
<hr>

And so is this:
<h1>Hello</h1>
<a href="whatever">Stupid link</a>
<hr>

The key is the presence of <h1> or <p> followed immediately
by <hr>.  Probably affects other format containers too but I 
haven't tested them all.

Trace output follows for the </h1><hr> case:

That's all -trace said before Lynx died.

Thank you, Fote.
