Thread 'tokio-runtime-worker' has overflowed its stack

[ss025]

Hi ,

I am getting thread 'tokio-runtime-worker' has overflowed its stack
fatal runtime error: stack overflow. I am not sure which code path is creating this. Any idea of how to identify code path?

Tried with RUST_BACKTRACE=full but no luck.

Well one potential cause would of course be infinite recursion, but barring that, it sometimes happen if you try to use large stack arrays in code like this:

let mut buf = [0; 1024];
loop {
    let len = stream.read(&mut buf).await?;
    ...
}

if you have such loops, try using a Vec<u8> or Box<[u8]> instead of the stack array.

Thanks for reply. I am not using stacks in loops. Same code was working . Just compiled again and new binary stopped working. Still trying to figure out which code piece is actually causing this.

Looks like issue was from third party which recently changes their impl using self in fmt::Display.
