Hi all,

i'm not sure if visa@ diff have anything to do with this but if I execute
ping -R 192.168.11.2 it always ends with Segmentation fault.

# ping -R 192.168.11.2

this is not problem but from time to time it ends up in some loop and i
need to kill ping ... ktrace from this ping is cca 250MB :)
