Compiler panics on 1.52.0 after cargo run and any file edit

[kykosic]

Apologies as this is the most minimal example I've been able to produce; working on finding a better one that doesn't use the kube-rs crate.

Steps to reproduce:

cargo clean
cargo run
touch src/main.rs
cargo run

The second cargo run will give ICE.

Code

use anyhow::Result;
use k8s_openapi::api::core::v1::Node;
use kube::api::{Api, ListParams};
use kube::Client;

#[tokio::main]
async fn main() -> Result<()> {
    let client = Client::try_default().await?;
    let api = Api::<Node>::all(client);
    let params = ListParams::default();
    let _ = api.list(&params).await?;
    Ok(())
}

[package]
name = "scratch-paper-2"
version = "0.1.0"
authors = []
edition = "2018"


[dependencies]
anyhow = "1.0"
k8s-openapi = { version = "0.11.0", default-features = false, features = ["v1_19"] }
kube = "0.52"
tokio = { version = "1.0", features = ["rt-multi-thread", "macros"] }

EDIT1: Thanks @Jake-Shadle for pointing out the issue is unrelated to rust-analyzer; any file change after the first cargo run will cause the issue.

[Aaron1011]

This is a known issue - unfortunately, there isn't a fix for it at the moment. As a workaround, you can run cargo clean -p <your_crate_name>, which will allow you to compile it.

[Jake-Shadle]

We are seeing the same issue, note that I don't believe it has anything to do with rust-analyzer specifically, rather that the first build succeeds, then any edit which requires a new build will fail.

Eg

cargo build -p crate-name <- succeeds
touch src/lib.rs
cargo build -p crate-name <- ICE
cargo clean -p crate-name
cargo build -p crate-name <- succeeds

[kykosic]

@Jake-Shadle I can confirm this also happens with me. I will edit the rust-analyzer bit out of the original issue.

#83291

[wesleywiser]

Thanks for filing the bug report! We just shipped a patch release to work around this issue and are currently triaging related issues related to ensure each underlying problem gets resolved. Since this appears to be a duplicate of #83538, I'm going to close in favor of that issue.
