error[E0308]: mismatched types
--> $DIR/upcast_soundness_bug.rs:59:13

LL | let p = p as *const dyn Trait<u8, u16>; // <- this is bad!
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected `u8`, found `u16`

= note: expected trait object `dyn Trait<u8, u8>`
found trait object `dyn Trait<u8, u16>`
= help: `dyn Trait<u8, u16>` implements `Trait` so you could box the found value and coerce it to the trait object `Box<dyn Trait>`, you will have to change the expected type as well
