Steps

1. git clone https://github.com/Andy-Python-Programmer/aero
2. cd aero
3. code .
4. Open ./src/aero_kernel/src/arch/x86_64/interrupt/ipi.rs and same for ./src/aero_kernel/src/arch/x86_64/interrupt/irq.rs

[ERROR proc_macro_api::process] proc macro server crashed, server process state: Ok(None), server request error: Os { code: 232, kind: BrokenPipe, message: "The pipe is being closed." }

(edit same issue for ./src/aero_kernel/src/syscall/mod.rs)
(edit (2) happens for every proc macro tested even with StructOpt)

Duplicate of #8929 and probably #8930. Can you try testing with #9047? Unfortunately, we can't merge that right now.

You can also try to downgrade to an older nightly.

Hopefully this helps someone out- I just confirmed presence of the issue on rust-toolchain nightly-2021-05-29 and absence on nightly-2021-05-17.
