Does this crash in the front end or at runtime?

If it crashes in the front end, that's a front end bug and we should figure out
why it's happening.

If it crashes at runtime, maybe we should change this to "RuntimeError, Pass" so
that at least we continue to validate that the front end doesn't crash.
