Compiler cannot pretty print

[mark-christiaens]

I'm trying "rustc --pretty typed example.rs > example.typed.rs" and the compiler gives up with "error: internal compiler error: node_id_to_type: no type for node expr 1u (id=23)"

The input program is:

use std::io::BufferedReader;
use std::io::File;
use std::task::try;

fn main() {
let result = try (proc () {
println!("Reading pairs");
let pairs = read_int_pairs();
println!("Printing {} pairs", pairs.len());
for &(a,b) in pairs.iter() {
println!("{:4.4d}, {:4.4d}", a, b);
}
});

if result.is_err() {
println!("parsing failed");
}
}

fn read_int_pairs() -> ~[(int,int)] {
let mut pairs = ~[];
let path = Path::new(&"foo.txt");
let mut reader = BufferedReader::new(File::open(&path));

loop {
let line_err = reader.read_line ();
match line_err {
Ok (line) => {
let fields = line.words().to_owned_vec();
if fields.len () == 2 {
let i1_opt = from_str::(fields[0]);
let i2_opt = from_str::(fields[1]);
match (i1_opt, i2_opt) {
(Some(a), Some(b)) => pairs.push((a,b)),
_ => fail! ()
}
}
}
Err (err) => {
println!("error reading: {}", err);
break;
}
}
}
pairs
}

I'm using a build from the master branch:

rustc --version
rustc 0.10-pre (8786405 2014-02-23 03:36:56 -0800)
host: x86_64-unknown-linux-gnu

Built from rev.

Seems like dup of #7754. (println! generates fixed-length arrays which currently cause errors with --pretty typed.)

This is indeed a dupe.
