Greetings. Here's what I get with gdb on the file:

http://www.safetycare.com.au/mig.html

with my debug-complied lynx:

I have no idea what lynx is doing, what the problem is, or how to
fix it... except maybe add a check for a NULL "p" before the for(..)
Or is there a patch that already fixes this? Wizards?

Take care.

P.S. I found a bug or two in mb007 and added a little nice touch to
saving sub-bookmarks (decription gets put in the title) and 008 will
be out RSN.
