Rustc endless loop out-of-memory and consequent SIGKILL in generic new type #67690
Description
Hi, i have made some changes for a crate stubborn-io to support a generic type that implements ToSocketAddrs from Tokio, but suddenly the code can't compile because it runs out of memory with 6, 8, 10 GB.
This is the code i'm trying to compile:
use super::io::{StubbornIo, UnderlyingIo};
use std::future::Future;
use std::io;
use tokio::net::ToSocketAddrs;
use std::pin::Pin;
use tokio::net::TcpStream;
impl<A> UnderlyingIo<A> for TcpStream
where A: ToSocketAddrs + Sync + Send + Clone + Unpin + 'static {
fn establish(addr: A) -> Pin<Box<dyn Future<Output = io::Result<Self>> + Send>> {
Box::pin(TcpStream::connect(addr))
}
}
pub type StubbornTcpStream<A: ToSocketAddrs + Sync + Send + Clone + Unpin + 'static> = StubbornIo<TcpStream, A>;
if changed the type A for SocketAddr or String it then compiles and runs fine.
It fails to compile on x86_64-unknown-linux-gnu with stable, nightly.
I'm attaching the Heaptrack files for further analysis.
