As a sanity check, I reran the gcc tests as a regular user (kernel 4,17,10; glibc-2.27). I still got the two g++ test failures above, but none of the libstdc++ tests failed:

I found a short fix for the g++ test and we can use that. I'm going to try running the tests as user nobody in a full build. We might be able to get a clean set of tests,
