0.2.7.5 cannot work inside lxc container

I am running tor inside a lxc container running ubuntu/vivid and Tor don't run since system tor status show it running

Tor version 0.2.7.5 (git-6184c873e90d93b2)

before upgrading to this version, everything work well inside the container. Outside of the container, in a host running ubuntu/vivid, everything work.

output of journalctl :
