[Mitch Phillips via Phabricator via llvm-commits]

hctim added a comment.

https://lab.llvm.org/buildbot/#/builders/5/builds/9643

You might find the instructions at https://github.com/google/sanitizers/wiki/SanitizerBotReproduceBuild helpful, as the MSan bot requires multiple stages of compilation.
