Bug
FnCtxt::pointer_kind hits todo!("FIXME(unsafe_binder)") for ty::UnsafeBinder(_). Any pointer cast whose pointee (or unsizing tail) is an unsafe binder ICEs at compile time.
Location
compiler/rustc_hir_typeck/src/cast.rs:121
Impact
ICE (not graceful diagnostic) for unsafe_binder feature users on ptr/ptr or ptr/addr casts.

Stub added when unsafe binder type was wired into typeck (9a1c5eb5b385).
Suggested fix
Return appropriate PointerKind (likely thin, or recurse into binder inner type) or emit a normal feature/diagnostic error via ErrorGuaranteed instead of todo!().
