Panic when trying to `use` macro

[jD91mZM2]

The compiler panicked

I tried this code:
compiler-crash tag on rust-nix.
cargo test

I expected to see this happen: A normal compilation error
Instead, this happened: The rust compiler panicked

Minimal reproduction example:

#![feature(rust_2018_preview)]

macro_rules! m {
    () => {}
}

mod m {
    use crate::nonexistent_module::m;

    fn f() {
        m!();
    }
}
