--- Comment #5 from Davide Italiano <davide at freebsd.org> ---
I don't think this is really invalid.
If this code passes the verifier, it should never crash in the backend.
So, either we reject this code in the verifier, or we bail out in the backend.
But I think a crash is still a legitimate bug, independently from the fact that
the code might exhibit UB.
