ICE due to mapping `f32` to same ident with `const` and `let` #108683

JulianKnodt · 2023-03-02T23:58:10Z

While technically this could shouldn't compile, it shouldn't ICE

Code

fn main() {}
fn example(
    planarity_epsilon: f32
) -> f32 {
    (0..10).map(|_| {
        const EPS: f32 = 3e-2;
        let EPS = planarity_epsilon;
        let z = 0.01 * EPS;
        return z;
    }).sum::<f32>()
}

I can only repro this on the playground, not on a local build or nightly, or godbolt for that matter. Are there special repro instructions?

matthiaskrgr · 2023-03-03T05:55:56Z

Ran this through icemaker and it says you need the --edition=2021 flag ^^

JulianKnodt · 2023-03-03T07:03:46Z

It happened locally on WSL with the latest nightly on a not-minimized version before I tried it on the playground

clubby789 · 2023-03-03T14:03:34Z

Minimized to

fn example(var: i32) {
    || {
        let 0 = var;
    };
}

(still requires Rust 2021. Error message is different but ICE looks the same)

regardless of edition prevents the ICE.
