It seems like there are a lot of failures in
the  teeks99-02-dc5-1z-lc-Docker-64on64 (clang 5, -std=c++1z
-stdlib=libc++) that aren't in the teeks99-02-dc5-1z-Docker-64on64 (clang
5, -std=c++1z)...and that is the only config that uses libc++, so I'm
guessing it is an issue with the libc++ install on that docker image.

I'll look at it when I get a chance...if anyone else has experience setting
up libc++ on ubuntu I'd be happy to take a pull request for the docker
image or command arguments:
