Description
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
}
