Sure ? Do have try cut and paste my example into xterm ?

Both addresses are work:

vbook#/sys/i386/compile/VBOOK 153_> ping -R -S 1.1.1.1 127.0.0.1
PING 127.0.0.1 (127.0.0.1) from 1.1.1.1: 56 data bytes

(use loopback not best way to do this, but you can try any interface)

Same setup works well on 4-STABLE
