bug report: rustc panic when run cargo check --all-targets

[Sherlock-Holo]

I am using nightly version: rustc 1.45.0-nightly (ad4bc33 2020-06-01)

I tried run cargo check --all-targets with this codes:

#[cfg(test)]
mod tests {
        #[async_std::test]
    async fn identify() {
        const IDENTIFY_BODY: &str = r#"
        {
  "client_id": "test",
  "deflate": false,
  "deflate_level": 6,
  "feature_negotiation": true,
  "heartbeat_interval": 30000,
  "hostname": "test-host",
  "long_id": "test",
  "msg_timeout": 0,
  "output_buffer_size": 16384,
  "output_buffer_timeout": 250,
  "sample_rate": 0,
  "short_id": "test",
  "snappy": false,
  "tls_v1": false,
  "user_agent": "nsq_tail/1.2.0 go-nsq/1.0.7"
}
        "#;

        const IDENTIFY_HEADER: &[u8; 8] = b"IDENTIFY";

        let len = IDENTIFY_BODY.len() as u32;
    }
}

I expected to see this happen: check successfully

Instead, this happened:

I believe this is related to #71948 but I couldn't reproduce it with your example on my local. Is this still happen when you try cargo clean or so? And it'd be great if you could also provide the targets you install.

[Sherlock-Holo]

When this bug happened, I'm testing the unit test in my project, but when I copy the unit test codes to an empty rust project, the cargo check --all-targets success, it makes me confused, so I run cargo clean but the problem still exists.

The targets what I install is nightly-x86_64-unknown-linux-gnu

And it doesn't cause problem with stable rustc rustc 1.43.1 (8d69840ab 2020-05-04)

[JohnTitor]

And it doesn't cause problem with stable rustc rustc 1.43.1 (8d69840 2020-05-04)

Yeah, that PR is on nightly only now. So, current master contains a fix for that PR (#72775), could you try to check with the master? You can try it with rustup-toolchain-install-master: https://github.com/kennytm/rustup-toolchain-install-master
If it still happens with the master, we should make another fix.

[Sherlock-Holo]

Will tomorrow nightly version contain this fix? if it contains I will try it tomorrow

[JohnTitor]

Will tomorrow nightly version contain this fix? if it contains I will try it tomorrow

Yes, it's your option.

[Sherlock-Holo]

@JohnTitor rustc 1.45.0-nightly (fe10f1a 2020-06-02) has fixed the problem

[JohnTitor]

Cool, then closing as fixed.
