Internal compiler error: unexpected panic

[robertazzopardi]

Happened today trying to build a current project of mine. Creating and building a new project works on stable, but produces the following error on nightly regardless of whether it is a fresh project or not.

Code

fn main() {
    println!("Hello, world!");
}
