Thanks for reporting the crash.

The vectorizer pass is empty at this point. It will just try to create
Sandbox IR and will quit. The crash is in the Sandbox IR creation phase,
which is still incomplete and under development. But thanks for reporting
the crash, it will help us with our Sandbox IR testing.
