Result in example file change when removing assert_eq!()

[veryhumanprogrammer]

I noticed that removing the assert_eq!() in the basics.rs example on line 80 caused the printed values to change.
Not sure if this is intended, but it doesn't seem like it. I'm quite new to Rust so maybe I missed something, but I am unable to explain why this happens.

This is the part of the code in basic.rs I mean

    for idx in 0..WORK_SIZE {
        if idx < RESULTS_TO_PRINT {
            println!("source[{idx}]: {:.03}, \t coeff: {}, \tresult[{idx}]: {}",
            vec_source[idx], COEFF, results[idx], idx = idx);
        }
        assert_eq!(vec_source[idx] * COEFF, vec_result[idx]);
    }

If I change it to this, the printed values change

    for idx in 0..WORK_SIZE {
        if idx < RESULTS_TO_PRINT {
            println!("source[{idx}]: {:.03}, \t coeff: {}, \tresult[{idx}]: {}",
            vec_source[idx], COEFF, results[idx], idx = idx);
        }
    }

However, if I change it to this it doesn't change

    for idx in 0..WORK_SIZE {
        if idx < RESULTS_TO_PRINT {
            println!("source[{idx}]: {:.03}, \t coeff: {}, \tresult[{idx}]: {}",
            vec_source[idx], COEFF, results[idx], idx = idx);
        }
        let test = vec_source[0] * COEFF;
    }

Normal printed values:

Altered printed values:

The line of code I'm talking about:

ocl/ocl/examples/basics.rs

Line 80 in f495254

assert_eq!(vec_source[idx] * COEFF, vec_result[idx]);

Very interesting. Thanks for reporting. We'll see if anyone else experiences this.

I can't reproduce.

Still having this issue?
