The behavior here depends on the platform and may also differ between
fast and slow paths [0]. Crash to let the fuzzer know there's nothing
interesting here.

[0] The reason for the fast-slow-path difference is that sometimes we
may trigger different compile jobs on these paths. One example is
`split`, which creates a new regexp instance on the slow path, but
reuses an existing instance on the fast path.
