Travis CI updated the clang compiler to use version 5.0 from 4.0. Because it added some new warnings, our builds on that variant are failing. I have been working on a fix and I have all of the warnings resolved, and now I'm down to a single test case failing.
As a result of the failure, I'm also adding a new docker script that uses ubuntu16 and clang 5.0. Anyways, the work is getting done in ORC-281. .. Owen
