This occurs because of the update to the addressing in ns of about 9/9/99.
I think that the ns team are getting rid of the notion of non extended and
extended addressing and making extended addressing the norm, although I'm
not sure about this.

I think that the fix is to change the above line to

sprintf(out, "%s recv %d %3.1f", name(),
         hdrip->saddr() >> Address::instance().NodeShift_[1],
     (Scheduler::instance().clock()-hdr->send_time) * 1000);

Haven't tried this, so I'm not sure if it works (specifically, I'm not
sure about the Address::instance() stuff), but a general rule seems to be
to change iph->src_ or iph->src() to iph->saddr() and iph->dst_ or
iph->dst() to iph->daddr().
