Panic when monomorphizing `HashMap` code

[jfecher]

Aim

use dep::std::collections::map::{ HashMap };
use dep::std::hash::BuildHasherDefault;
use dep::std::hash::pedersen::PedersenHasher;

fn main() {
    let map: HashMap<u64, u64, 10, BuildHasherDefault<PedersenHasher>> = HashMap::default();
    println(map == map);
}

Expected Behavior

The code to execute and print an empty hashmap.

Bug

The application panicked (crashed).
Message:  internal error: entered unreachable code: Failed to find trait impl during monomorphization. The failed constraint(s) are:
  BuildHasherDefault<PedersenHasher>: BuildHasher
Location: compiler/noirc_frontend/src/monomorphization/mod.rs:1022
