Awesome, thanks! I saw your post on `libcxx-dev` just now. To reproduce CI failures locally, you can use `libcxx/utils/ci/run-buildbot-container` to spawn a Docker container matching our CI nodes, and then `libcxx/utils/ci/run-buildbot <config you want>` to run the actual build/test. There's documentation in `run-buildbot-container` and also the `Dockerfile` in the same directory.
