So, now I have a new problem with current.

I just now updated my current sources and ran buildworld and buildkernel,
since Gleb fixed the WITHOUT_PF problem.

After installing the new world and kernel I see that ifconfig is dumping
a core, apparently when it tries to show lo0, since re0 is correctly
shown:

ifconfig
re0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 408=
8 options=3D82098<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>
        ether redacted
        inet 192.168.178.XXX netmask 0xffffff00 broadcast 192.168.178.255
Segmentation fault (core dumped)

Unfortunately, I see this error message when I try to look at the core
file with gdb:

gdb /sbin/ifconfig ifconfig.core
ld-elf.so.1: Undefined symbol "rl_eof_found" referenced from COPY
relocation in /usr/local/bin/gdb

pkg claims that my packages are all up to date.

Not exactly a fatal error, but still rather surprising.
