Follow-up Comment #1, bug #31177 (project lwip):
In reviewing this change, I realised that I had not taken into account the
case where the active PCB list is empty after the PCB is removed. As a result,
the suggested fix should actually be:
prev = tcp_active_pcbs;
while(prev && (prev->next != pcb))
{
prev = prev->next;
}
