The daily job found a dhclient core file in / -- gdb says 

    Program terminated with signal 8, Floating point exception.
    #0  0x80494fa in ?? ()
    (gdb) bt
    #0  0x80494fa in ?? ()

Has anyone else seen anything like that?  (My dhclient is slightly 
modified, to deal with the buggy dhcp server that I've encountered in 
some Marriott hotels, but I don't think that that code was exercised 
here.)

If folks are interested, I could rebuild dhclient not stripped, to get 
a better traceback.  This is on a 1.6.1 system that I built from source.
