FWIW, this happens both on `upstream-with-swift` and on `stable`, so I think it's something important.

It's intermittent.
@vedantk is currently doing the plumbing for asan/ubsan in swift-lldb so we can flesh out all the issues and see if the problem is still there. I'm keeping this open in the meanwhile.
