Bug
In compiler/rustc_const_eval/src/interpret/, the comptime evaluation path contains a todo!() that will ICE if reached. This is behind the unstable #[comptime] feature gate, so it cannot be triggered by stable Rust code.
The todo!() exists because the comptime feature is under active development and certain paths are not yet implemented. This is intentional but should be tracked.
Impact
Latent ICE behind unstable feature gate. Cannot be triggered on stable.
