>Description:
When communicating with a BOOTP server, dhclient fails to configure
the interface (the BOOTP configuration works with Win98 and Linux)
and crashes.
Core dump shows:

>How-To-Repeat:
Should be deterministic, using BOOTP. Here's my bootptab:
.allhost:hd=/tmp:bf=null:\
:ds=10.0.0.1:\
:sm=255.255.255.0:\
:gw=10.0.0.1:\
:ts=128.130.2.3:\
:lp=10.0.0.1:\
:to=0:
devil:ht=1:ha=00409501B465:ip=10.0.0.4:tc=.allhost:
>Fix:
Contributed code, so ask the ISC to fix it. Seems like the lease time isn't
being used for BOOTP, but the dhclient crashes trying to use it.
