ice ice baby

[sjud]

Sorry, I'm not sure what code is causing this. Is it the code in the error before the ICE?
I had a private import of a pub type Arc<Box> and was trying to import it.

mod {
   use thing::TraitThing;
}

When I changed the use to a pub use my ICE stopped.

mod {
   pub use thing::TraitThing;
}

🤷

@sjud, please next time provide as much code as possible, and give the issue a descriptive title. there's not really much to work off in this issue.

[sjud]

Oops, sorry! This was a low effort bug report. :(
I'll try and replicate the error later. Thank you!
