Internal Compiler Error with neon-binding (https://github.com/neon-bindings/neon), Js-Rust Bindings #86071

Phil-Pa · 2021-06-06T19:12:53Z

How to reproduce:

npm init neon cpu-count
cd cpu-count
copy the code below in src/main.rs

General Info

I know that code might not make any sense. I just wanted to try if I could do some multithreading with JavaScript by calling rust code from JS. But nethertheless I reported the error, because it could be useful. And I got 2 backtraces and pasted it.

Code

use std::{os::unix::prelude::JoinHandleExt, thread::JoinHandle, time::Duration};

use neon::prelude::*;

fn hello(mut cx: FunctionContext) -> JsResult<JsString> {
    Ok(cx.string("hello node"))
}

static mut global_handle: Option<JoinHandle<FnOnce(_)>> = None;

fn start_thread(mut cx: FunctionContext) -> JsResult<JsNumber> {
    let handle = std::thread::spawn(move || {
        let mut i = 0u32;
        loop {
            std::thread::sleep(Duration::from_millis(300));
            i += 1;
            println!("{}", i);
        }
    });
    unsafe {
        global_handle = Some(handle);
    }
    Ok(cx.number(1f64))
}

#[neon::main]
fn main(mut cx: ModuleContext) -> NeonResult<()> {
    cx.export_function("hello", hello)?;
    Ok(())
}

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.54.0-nightly (b663c0f4f 2021-05-29) running on x86_64-unknown-linux-gnu

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental --crate-type cdylib

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
end of query stack
thread panicked while panicking. aborting.
error: could not compile `cpu-count`

@Phil-Pa you must edit src/lib.rs not src/main.rs.

hellow554 · 2021-06-07T07:17:33Z

MCVE:

use std::thread::JoinHandle;

static GLOBAL_HANDLE: Option<JoinHandle<FnOnce(_)>> = None;

fn main() {}

bisected to nightly-2020-05-03 7f65393...f05a524

seems to be a duplicate or at least related to #83630

closing then as duplicate (but please reopen if not the case, Zulip discussion)
