[B.A.T.M.A.N.] -p ... crashes

[Lui]

Hi,

i've seen this behavior bevor, but couln't reproduce it until now:

If B.A.T.M.A.N.-III v0.1.1 beta2 (compability version 2)
is startet with a -p(refered gateway) option and the given gateway is (at least) 2 hops away
(may also not/-always/-directly reachable after start), batmand crashes.

This happens reproduceble ~30-60sec. after start.
Until this point routes are written.
No output. No purging of written routes.

Tests used: batmand -p <gateway> -r 2 eth1:bat br0:bat 

With a 1-hop-to-prefered-gateway enviroment batmand seems to have no problems...

Regards
Lui

could you send a core dump and your binary ?

How to create a core dump:
Connect to your device (via ssh) and type:
ulimit -c 20000
Afterwards start batmand with a debug level > 0, e.g.:
batmand -d 3 -p <gateway> -r 2 eth1:bat br0:bat
Wait until it crashed and you will find a file named "core" in your current 
directory which represents the state of batman in the moment when it crashed.
