@rkrasiuk What is the last nightly you considered? Following this, I've 1.72.0 and I've no error running cargo clippy --all --all-features

[rkrasiuk]

i've run it on rustc 1.72.0-nightly (839e9a6e1 2023-07-02) <- date matters

The incorrect implementation of clone on Copy type errors are from parity's fixed-hash crate. construct_fixed_hash implements clone by creating a new fixed hash with zero bits rather than dereferencing self (replace clone function body with *self).

Not sure if changing this behavior would screw things up elsewhere though.
