Tweaked trait example from tutorial fails in rustc/back/rpath.rs

[orpheuslummis]

Code taken nearly as-is from tutorial, commit 39acb06.

trait Printable {
    fn print();
}

impl int: Printable {
    fn print() { io::println(fmt!("%d", self)); }
}

fn main() {
    10.print();
}

What operating system are you using?

[nikomatsakis]

Hmm, linux I guess, based on the output.

After re-installing Rust, I'm now failing to replicate the crash. The problem was almost certainly an "old library lurking around mucking things up". Closing.
