Hey ae,

Thanks for your detailed reports, especially the nice Python
reproducer you sent. And sorry for the delay in getting back to you
and investigating this. I actually don't receive any of your emails. I
don't know if it's because mail.ru has a bad spam score, or because
the HTML part of your email contains embedded javascript, but there's
something sufficiently sketchy that precludes them from being
delivered to my mailbox. Luckily others on the list brought this
thread to my attention.

I successfully debugged and fixed the Python reproducer you sent me.
Could you try the following patch, and see if applying it results in
ospfd working properly?
