cargo-asm panics on unwrapping a directory

[ernieIzde8ski]

I wrote the following program:

use std::f64::consts::{E, PI};

fn power_squared(a: f64, b: f64) -> f64 {
    a.powf(b).powf(2.0)
}

fn doubled_exp(a: f64, b: f64) -> f64 {
    a.powf(b * 2.0)
}

fn main() {
    println!("{}", power_squared(E, PI));
    println!("{}", doubled_exp(E, PI));
}

and I tried to get the assembly for the former function, which caused a panic:

[2 0] ernie@vivec% cargo asm --build-type=debug playground::doubled_exp

cargo-asm is no longer maintained, you can try cargo-show-asm instead.
