[HW4] Couldn't Compile cargo test --test boc due to non-existent object file?

I run cargo test --test boc, but I faced with the following error:

error: could not compile cs431-homework (test "boc") due to 1 previous error`

I tried to google the error, but couldn't get any results. I believe the reason for this error is because of lldb debugger on vscode-remote. Previously, I didn't have any problems with complications, but later when I tried to debug a unit test by lldb, after a few successful tries, it showed an error: linking with cc failed: exit status: 1. I saw this reply on Github Issue: rust-lang/rustup#3581 (comment)
But I don't know what I am supposed to do at this point, since it is not the exact problem.

[Lee-Janggun]

Does running cargo clean first and trying again work?

This is an ICE, so it's a Rust error. So hopefully that fixes it...

[Coll1ns-cult]

Yes, It worked, thanks for this!
