`cargo test --no-run` sometimes gets SIGKILL out of thin air on MacOS

[matklad]

Problem

In xshell, my macos builds fail fairly frequently with

command was terminated by a signal `cargo test --workspace --no-run`: 9

See, eg

https://github.com/matklad/xshell/runs/5529460783?check_suite_focus=true#step:4:22

What specifically happens here is that GitHub actions invokes cargo run --example ci, and that example recursively invokes cargo test --run, which then gets killed.

It seems like this is something we saw previously in https://github.com/rust-lang/cargo/issues/7821 and https://github.com/rust-lang/cargo/issues/10060.

Opening this issue to signal that this doesn't seem to be entirely fixed!

Can you get the system logs? I don't know offhand how to get those from GitHub Actions. Normally I record them locally using console.app.

I see sh.remove_path("./target")?; in your script. One possibility is that the provenance for the executable is lost (for the temporary signatures). Perhaps consider using a separate target directory instead?

This also happens to me, cargo t (I don't use --no-run) randomly dies:

failures:

---- src/lib.rs - (line 44) stdout ----
Test executable failed (signal: 9 (SIGKILL)).


failures:
    src/lib.rs - (line 44)

test result: FAILED. 4 passed; 1 failed; 0 ignored; 0 measured; 0 filtered out; finished in 1.45s

I was also able to intermittently reproduce this when using cargo test --doc from this minimal example:

//! ```
//! use crate::this;
//! let foo = this::add(1,2);
//! assert_eq!(3, foo);
//! ```

pub fn add(left: usize, right: usize) -> usize {
    left + right
}

However, without anything changing on my system to my knowledge (i.e. the same session). It started succeeding without fail. Notably this was after I started trying to capture the system logs via Console.app.
