Reading invalid GZ file causes infinite loop iteration

[mikemiles-dev]

Please refer to this discussion: https://users.rust-lang.org/t/flate2-bufreader-issue-possible-infinite-loop-bug/17804/13

Code to reproduce:

extern crate flate2;

use std::io::{BufRead, BufReader};
use std::path::PathBuf;
use std::fs::OpenOptions;
use flate2::read::GzDecoder;

fn main() {
	let path = PathBuf::from("./empty.gz");

    let file = OpenOptions::new()
        .read(true)
        .open(&path).unwrap();
    let cbjson = GzDecoder::new(file);

    let reader = BufReader::new(cbjson);

    let stream = reader.lines().enumerate().map(move |(i,line)| {
        println!("LINE {} {:?}", i, line);
    });

    for result in stream { }
}
