I've gathered several core dumps now but the stacktraces are identical.
The logged reason for dumping core is "free(): invalid pointer".
I wonder if there is a race condition with whatever networkd itself is
doing when it reconfigures the interface (which it seems to do more
aggressively for DHCP renewals than it used to) and what my scripts in
/etc/networkd-dispatcher/configured.d and /etc/networkd-
dispatcher/configuring.d are doing. Assuming the
"routing_policy_rule_free" function is equivalent to "ip rule delete
..." there could be a conflict with my "configuring.d" script in
particular. The "configured.d" script adds some extra routing policy
rules and the "configuring.d" script deletes them so they aren't
duplicated every time the network is configured.
