Degradation from rustc 1.71.0 -> 1.79.0 ("infinite space" compile error not recognized anymore) #127910
Description
Behaviour in rust version 1.79.0 (the bug)
I found a program that does
- successfully finish
cargo check - but does never build (it takes up as much space as it can get, and then inevitably crash)
on rust version 1.79.0:
rustc 1.79.0 (129f3b996 2024-06-10)
binary: rustc
commit-hash: 129f3b9964af4d4a709d1383930ade12dfe7c081
commit-date: 2024-06-10
host: x86_64-unknown-linux-gnu
release: 1.79.0
LLVM version: 18.1.7
Behaviour in rust version 1.71.0 (before the degradation)
On rust version 1.71.0 this program failed the cargo check and build, which is the expected behaviour imo.
The minimum working example
use std::io::{self, BufRead};
fn main() -> Result<(), io::Error> {
let stdin = io::stdin(); // We get `Stdin` here.
let mut iterate_in = stdin.lock().lines();
// that's how to run a single request for a number alone in a line
let count = iterate_in.next().unwrap().unwrap().to_string().parse::<usize>().unwrap();
let mut rects = vec![];
for _ in 0..count {
let vecline = iterate_in.next()
.unwrap()
.unwrap()
.split_whitespace()
.map(|s| s.parse::<u32>().unwrap()-1)
.collect();
let el = (rects[0],rects[1],rects[2],rects[3]);
rects.push(el);
}
if let Some(solution) = rects.to_string() {
for s in solution {
println!("{} {}", s.0+1, s.1+1);
}
}
Ok(())
}
