Today I updated my test suricata to PR/3448.

Regarding *segfault* now I think that it was my fault, cause I was running
other instance on the same host monitoring the same interfaces. Today I
switched off the other suricata and everything worked as expected.

Unfotunatelly -T switch keeps getting errors:
network-sensor suricata # suricata -c suricata.yaml -T
