auto-reduced (treereduce-rust):

fn f() -> isize {
    let mut x: isize;
    for _ in 0..0 {
        let s = [(); {
            let mut n = 113383;
            while n != 0 {}
            n
        }];
    }
    return x;
}

fn main() {
    f();
}

original:

fn f() -> isize {
    let mut x: isize;
    for _ in 0..0 {
    // Tests the Collatz conjecture with an incorrect base case (0 instead of 1).
    // The value of `n` will loop indefinitely (4 - 2 - 1 - 4).
    let s = [(); {
        let mut n = 113383; // #20 in https://oeis.org/A006884
        while n != 0 {
            //~^ ERROR is taking a long time
            n = if n % 2 == 0 { n / 2 } else { 3 * n + 1 };
        }
        n
    }];

    s.nonexistent_method();
}
    return x; //~ ERROR E0381
}

fn main() { f(); }
