Hello,

I was working on my toy project here:
https://github.com/smukherjee2016/sayo_pbr_rs

The project was compiling and running fine at this commit:
smukherjee2016/sayo_pbr_rs@e8f071c

However, I decided I wanted to move functionality out of src/lib.rs and into src/scene/mod.rs, so I moved all of it except the mod declarations, and then tried to compile. This led to the compiler panic.

The repro commit for this:
smukherjee2016/sayo_pbr_rs@ecf225f

I am using CLion, and the command I run is simply cargo run.

I am pretty new to Rust so it might just be me doing something really wrong, but it'd be great if someone could look into this and advise. Thank you!

I have a PR that will fix the underlying problem, but we need to come up with a reproduction case to avoid regressions in the future.

Thank you so much for the super-fast response! However, I am not at all familiar with rust's compiler code, so if you could tell which part of the code the compiler trips upon, I can try isolating that part of the code to make a smaller reproducible example.

Reduced it down to two files:

src/main.rs: (replace enter_crate_name_here obvisouly ^^)

use \enter_crate_name_here\;

fn main() {}

src/lib.rs:

pub use u32;

u32 can be any primtive type as u8, usize, i32, f64. Haven't managed to get it down to one file sadly :/

is there a problem of adding the test in two files (with aux-build)? if not, I could try to work on this as a first issue.
