Memory overflow when compiling

[tronta]

When compiling this code the compiler starts using more and more memory trill it gets terminated by signal: 15, SIGTERM: termination signal
That's the best minimal code I could come up with...

Code

use actix_web::{web, App, HttpServer, Responder};
use mongodb::Client;

async fn get(
    client: web::Data<Client>,
) -> impl Responder {
        let _ = client
            .clone()
            .database("123")
            .collection("456")
            .find(None, None)
            .await;
    String::new()
}

#[actix_rt::main]
async fn main() -> std::io::Result<()> {
    let client = Client::with_uri_str(&"path").await.unwrap();

    // Start http server
    HttpServer::new(move || {
        //   let auth = HttpAuthentication::bearer(validator);

        App::new()
            .data(client.clone())
            .route("/", web::get().to(get))})
    .bind("127.0.0.1:8000")?
    .run()
    .await
}

This sounds a lot like #75808 and #75992

I also have this problem.
Temp fix by downgrading to 1.45.0 using:

• rustup install 1.45.0
• rustup override set 1.45.0 (NOTE: run in project directory)
