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(); }

This doesn't seem const-eval related to me? The panic is nowhere near const-eval, as far a I can see?

Looks like some part of the pattern matching machinery is not properly dealing with the fact that the constant failed to evaluate due to an infinite loop.

Does the following code also cause an ICE for the same reason?

fn main() {
    let mut sum = 0;
    let a = [(); { loop {} }];
    for i in 0..a.len() {
        sum += a[i];
    }
}
