My test is the result of reducing a file with just "include <atomic>", just like in the PR.
It was fixed in r269059 which added a similar test, except mine does not use inheritance and is a bit simpler. So I figured it wouldn't hurt to cover more scenarios for this ICE. I ran the test in my build directory and received 4 passes and 1 unsupported test, which was expected.
