[Olsr-users] olsrv2: segfault when a link goes down

[Vigneswaran R]

Hello,

I cloned the olsrd git repository and testing the olsrv2 implementation 
(olsrv2 branch) *** olsr.org - pre-0.7.0-44408ef ***.

I am trying to measure the time taken to re-establish the routes when  a 
link goes down and come back again. However, as soon as I unplug the 
network cable from an interface (or execute 'ip link set eth0 down'), 
olsrd exits with segmentation fault with the following information.

<snip>
10:13:55.914 INFO(interface) src/interfaces.c 317: Removing interface eth0
10:13:58.818 INFO(packet_creation) src/mid_set.c 499: Building MID

10:13:58.868 WARN(interface) src/linux/net.c 258: Could not restore

Segmentation fault (core dumped)

Please help me in fixing the problem.
