ifconfig seg faulting?

[Andy Holyer]

I just had a scamper to recover a FreeBSD 5.2 server (Dell Poweredge 
rack mount server, 1 GB RAM twin Gig Ethernet).

The only bit that's not right now is that every time we run ifconfig, 
it has a segmentation fault and dumps core.

Example:


 > ifconfig -a
em0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
         options=3<RXCSUM,TXCSUM>
         ether 00:c0:9f:39:f4:e8
         media: Ethernet autoselect
         status: no carrier
Segmentation fault (core dumped)
 >

You can specify a particular interface, that reports correctly, and 
then dumps core.

Anyone seen anything like this? Any hints gladly received.
