>Description:
The setfib utility coredumps if the supplied routing table is greater then the maximum table number in the system.

In my case the kernel was compiled with options ROUTETABLES=4, so any time I call setfib with fib >= 4 it coredumps.

>How-To-Repeat:
Compile kernel with options ROUTETABLES=4 and then:

-bash-3.2$ setfib 4 netstat -rn -f inet
setfib: Segmentation fault: 11 (core dumped)
