I am not sure that is an issue, it was more about figuring out if there is a proper value set for the avp, not to be a pointer to an array or a map/hash-table, which can lead to illegal memory ops.
The real issue seems to cause random side effects, which typically is because of a race or buffer overflow. Having log errors like `unknown address family 0` or `null bind_address` should not happen. Would you be able to test with git master branch? It has more debug logs, nightly debs are built for it and made available on deb.kamailio.org
