Follow-up Comment #2, bug #59468 (project lwip):
I get a similar error on line 199 where p != NULL but p->payload = NULL. I can
replicate this with a large ping: ping -s 5000 and then wait for the
ip_reass_remove_oldest_datagram() to get called.
Doesn't look like ipr contains the full datagram either. In my case, this only
happens for >3 fragments.
