Yes, it is working for me. I haven't got any segfault till now. However, 
I am not sure how to use the test cases to validate olsrd2. If I run 
test_nhdp_2, it says "10 tests ended: 10 successes, 0 fails" regardless 
of whether olsrd2 is running or not.

Attached the logs produced by both the new code (olsrd2_success.log) and 
the old code which gave segfault (olsrd2_failure.log). Thanks.
