> When the connection to the interior router goes down then the addr.edge_outlink link
proper is freed but the pointer to the link is still in the addr struct.
> Later when the addr is unbound the link is dereferenced causing a segfault.
> An attached log trace shows the events. Search for link _0x1c31210_ using mobile address
_M0e61_.
