Attempt to continue a labeled loop from within async block panics compiler #73704
Description
Description
I found the following compiler bug when attempting to continue a tagged loop from within an async block. In Coc I get a warning instead of an error for this. And when I try to compile the compiler panics. I tried on nightly as well and it seems to give the same error. If I change the continue to a break I get error `break` to unknown label as expected.
Code
pub async fn run(&self) {
'outer: loop {
match TcpStream::connect(self.addr).await {
Ok(mut stream) => {
trace!("Connected");
let (mut reader, mut writer) = self.get_framed(&mut stream);
let recv_loop = async move {
while let Some(item) = reader.next().await {
match item {
Ok(inner) => self.broadcast_msg(inner).await,
Err(err) => self.broadcast_decode_error(err).await,
}
}
};
let send_loop = async move {
let outbound_stream = self.outbound_ch.subscribe().await;
pin_mut!(outbound_stream);
while let Some(cmd) = outbound_stream.next().await {
match cmd {
Command::Msg(mut cmd) => {
if let Err(err) = writer.send(cmd.cmd).await {
if let Some(notify) = cmd.notify.take() {
if let Ok(notify) = Arc::try_unwrap(notify) {
let _ =
notify.send(Err(SendError::CodecError(err)));
}
}
} else {
if let Some(notify) = cmd.notify.take() {
if let Ok(notify) = Arc::try_unwrap(notify) {
let _ = notify.send(Ok(()));
}
}
}
}
Command::Reconnect => {
continue 'outer;
// ^ ------------------------- This leads to the below bug...
}
}
}
};
let ping_loop = async move {
if let Some(ref token) = self.ping_token {
loop {

{
