Compiler panic in 1.72.0

Code

[package]
name = "untitled"
version = "0.1.0"
edition = "2021"

[dependencies]
tokio = { version = "1.15.0", features = ["full"] }
actix-web = "4"

[dependencies.sqlx]
version = "0.7.1"
default-features = false
features = ["postgres", "macros", "runtime-tokio", "chrono"]

use std::{env, io};
use std::net::Ipv4Addr;
use actix_web::{App, HttpResponse, HttpServer, post, Responder};
use actix_web::web::{Data};
use sqlx::{PgPool};

#[post("/upload")]
async fn upload(pool: Data<PgPool>) -> impl Responder {
    pub async fn find_country(dependencies: impl IntoIterator<Item = i32>, ex: &PgPool) {
        for id in dependencies {
            sqlx::query!("select * from countries where id = $1", id)
                .fetch_one(ex)
                .await
                .unwrap();
        }
    }

    let pool = pool.get_ref();
    let a = vec![0];
    let vec = a.iter().map(|x| *x);
    find_country(vec, pool).await;

    HttpResponse::Ok()
}

#[tokio::main]
async fn main() -> io::Result<()>{
    let uri = env::var("DATABASE_URL").expect("DATABASE_URL must be set");
    let pool = PgPool::connect(&uri)
        .await
        .expect("failed to create pg pool");
    let pool = Data::new(pool);
    HttpServer::new(move || {
        App::new().app_data(Data::clone(&pool)).service(upload)
    }).bind((Ipv4Addr::UNSPECIFIED, 8080))?.run().await
}

Changing IntoIterator to Iterator compiles. Removing the map call compiles. Seems to work if it is not a actix-web route. Using the query function instead of the macro also fails.
