The DEP-8 tests will be more suitable to be submitted to the development version, so I'll split them from here.

While working on a more specific test for this instead of the ones submitted for review, Sergio discovered that the error wasn't enough reproducible with the following

netflix-nov6.conf:
# Null AAAA response on these domains
server=/netflix.com/#
address=/netflix.com/::
server=/netflix.net/#
address=/netflix.net/::
server=/nflxext.com/#
address=/nflxext.com/::

It needs another double line of server/address: with that, we always get the segmentation fault.

The bad news are that the proposed patch doesn't mitigate the error... so it would need another change introduced in upper versions. Looking for that change now.
