Running tests using Bevy 0.14.0 fails on Windows

[janhohenheim]

Setup

Cargo.toml

[package]
name = "minimal_doctest_fail"
version = "0.1.0"
authors = ["Jan Hohenheim <[email protected]>"]
edition = "2021"

[dependencies]
bevy = { version = "0.14.0", features = ["dynamic_linking"] }

[profile.dev]
opt-level = 1

[profile.dev.package."*"]
opt-level = 3

lib.rs

/// ```
/// use bevy::prelude::*;
/// 
/// App::new().add_plugins(DefaultPlugins);
/// ```
pub struct Foo;

• Add the output of rustc-clif --print target-libdir to my PATH per Dynamically linked library path resolution with cargo clif test --doc differs from cargo test --doc #1505
• Run cargo clif test --doc

Result

test src\lib.rs - Foo (line 1) ... FAILED

failures:

error: doctest failed, to rerun pass `--doc`

Additional Notes

I don't know if the fact I'm using dynamic linking is relevant for this issue.

Update: Managed to generate a smaller example that results in another error, but it pulls in another dependency:

Cargo.toml

[package]
name = "minimal_doctest_fail"
version = "0.1.0"
authors = ["Jan Hohenheim <[email protected]>"]
edition = "2021"

[dependencies]
# remove the `dynamic_linking` feature to fix the issue.
bevy = { version = "0.14.0", features = ["dynamic_linking"] }
avian3d = { git = "https://github.com/Jondolf/bevy_xpbd", branch = "avian"}

[profile.dev]
opt-level = 1

[profile.dev.package."*"]
opt-level = 3

lib.rs

/// ```
/// use bevy::prelude::*;
/// use avian3d::prelude::*;
/// 
/// App::new().add_plugins((MinimalPlugins, PhysicsPlugins::default()));
/// ```

This results in the following:

For context, Avian is one of the two major physics engines for Bevy.

[janhohenheim]

I don't think you know how this happened @Jondolf, but Avian is causing some interesting runtime failures on cranelift.

[bjorn3]

I suspect the crash is unrelated to Avian. Are you able to get a backtrace? Does it reproduce if you move from a doctest to a standalone integration test?

[janhohenheim]

@bjorn3 running the following does indeed also trigger the first error:

#[cfg(test)]
mod tests {
    use bevy::prelude::*;

    #[test]
    fn test_bevy() {
        App::new().add_plugins(MinimalPlugins);
    }
}

results in

running 1 test
thread 'main' panicked at library\test\src\lib.rs:607:31:
failed to spawn thread to run test: The parameter is incorrect. (os error 87)
stack backtrace:
error: test failed, to rerun pass `--lib`

Caused by:
  process didn't exit successfully: `C:\Users\conta\git\janhohenheim\minimal_doctest_fail\target\debug\deps\minimal_doctest_fail-2ce86e35ecdec25f.exe --nocapture` (exit code: 0xc000001d, STATUS_ILLEGAL_INSTRUCTION)

Adding the Avian part however does not change the error and thus does not replicate my finding posted before.

All of the above does not change when I move the test into tests/minimal_test.rs.

[janhohenheim]

@bjorn3 some updates: the error state_and_queue.addr() & STATE_MASK == RUNNING was confirmed to be also hit by the LLVM backend in rust-lang/rust#127979
I renamed the issue since the error The parameter is incorrect. (os error 87) can be replicated with regular tests.

[bjorn3]

Does it work now? There have been several bug fixes related to Bevy in the past couple of months.
