fn main() {
    let mut a = [0;10];
    a[5] = 5;

    let slice = & a[4..7];
    for i in 0..3 {
        println!("slice[{0}]:{1}",i,slice[i]);
    } 

    take(a);

    for i in 0..10 {
        println!("a[{0}]:{1}",i,a[i]);
    }

}


fn take (a [i32]){
//
}

I cannot reproduce the ICE on nightly or stable, please provide the error message and compiler-version. Also your example is missing a : between the a and the [i32] of the take function

Could not compile test.

To learn more, run the command again with --verbose.

Sure. But if I add it, rustc doesn't panic anymore. I'm just running through the tutorials, and am wildly trying things out. :-)

please update your rust compiler. I believe this has been fixed in #22544

Confirmed that this is fixed on stable and beyond, but thanks for the report!
