ICE: compiler/rustc_typeck/src/check/upvar.rs:1701:13: Drop location span error: need to handle more

[jaskij]

Code

Works even with calling just rustc - no need for a project, and does not need gpio_cdev as a dependency in Cargo.toml.

#![warn(rust_2021_incompatible_closure_captures)]

use std::time::Duration;

use gpio_cdev::{Line, LineRequestFlags};

fn main() {}

pub(crate) struct Numberer {
    line: Line,
    interval: Duration,
    step: u32,
}

impl Numberer {
    pub(crate) async fn new(
        line: Line,
        interval: Duration,
        step: u32,
    ) -> Result<Numberer, gpio_cdev::Error> {
        line.request(
            LineRequestFlags::INPUT,
            0,
            crate::build_info::BUILD_INFO.package_name,
        )?;
        Ok(Numberer {
            line,
            interval,
            step,
        })
    }
}

@jaskij:

I unfortunately do not have the time to minimize the code.

Do you have a codebase that can be shared instead? Unfortunately, it's kinda difficult to investigate this without seeing what triggered the ICE.

might be a duplicate of #93117

[jaskij]

@compiler-errors I tried my hands at minimizing this, and it turned out way easier than I thought. Updated the original comment with reproduction code.

[rvantonder]

I subscribed to this thread for curiosity about ICEs on rustc. Here's a smaller crashing program using comby-reducer 😄

#![warn(rust_2021_incompatible_closure_captures)]
impl Numberer {
    pub(crate) async fn new(
        interval: Duration,

[jaskij]

Managed to minimize it more:

#![warn(rust_2021_incompatible_closure_captures)]

fn main() {}

pub(crate) struct Numberer {}

impl Numberer {
    pub(crate) async fn new(
        interval: Duration,
    ) -> Numberer {
        Numberer {}
    }
