Default method results in: error: internal compiler error: method not found in AST map?!

[DaGenix]

Updated with a simpler test case:

ast_map_issue1.rs:

pub trait Digest {
    fn input(&mut self, in: &str);

    fn input_str(&mut self, in: &str) {
        self.input(in);        
    }
}

struct Sha2;

impl Sha2 {
    pub fn new() -> Sha2 {
        return Sha2;
    }
}

impl Digest for Sha2 {
    fn input(&mut self, in: &str) {

    }
}

ast_map_issue2.rs:

use ast_map_issue1::*;
mod ast_map_issue1;

#[main]
fn main() {
    let s = Sha2::new();
    s.input_str("hi");
}

This is producing the same error I saw before when using: 8883099.

Original:

While working on a SHA-2 implementation, I was trying to create some utility default methods on the Digest trait. However, I ended up getting the following error:

rust/src/libextra/workcache.rs:253:4: 253:37 error: internal compiler error: method not found in AST map?!
rust/src/libextra/workcache.rs:253 (sha).input_str(json_encode(t));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
make: ** [x86_64-unknown-linux-gnu/stage0/test/extratest-x86_64-unknown-linux-gnu] Error 101

I don't have a simple test case yet, but I'll try to develop one in the next few days.

In the meantime, the sha2-default-method-issue branch of https://github.com/DaGenix/rust.git will trigger this issue.

Possibly the same bug as #7481.

Oh, yeah. Same bug. Hadn't noticed this one, though, and discussion is on the other. Whoops. Closing as dupe.
