Are you building in debug mode? Can you provide an repro example?

[io0000]

1. debug mode

2. code snippet

fn call_with_one<F>(func: F) -> usize
    where F: Fn(usize) -> usize 
{
    let mut var1 = 1;
    var1 += 5;
    println!("var1:{}", var1);

    func(1)
}


fn main() {
    let double = |x| x * 2;
    let output = call_with_one(double);   
    println!("{}", output);
}
