cfallin opened issue #3191:

The Cranelift interpreter appears not to properly handle an overflow (from e.g. INT_MIN / -1), resulting in a panic rather than an explicit error type returned to the caller. Found via fuzzing.

In the implementation here, it appears that we need to check for this case specifically.
