'tokio-runtime-worker' has overflowed its stack fatal runtime error: stack overflow

[ss025]

Hi,

Upgrading to 0.5.3 is causing stack overflow error. After investigation, I found that in fmt::Display , it is calling self.

https://github.com/pimeys/a2/blob/master/src/error.rs

impl<'a> fmt::Display for Error {
    fn fmt(&self, fmt: &mut fmt::Formatter<'_>) -> fmt::Result {
        match self {
            Error::ResponseError(Response {
                error: Some(ErrorBody { ref reason, .. }),
                ..
            }) => write!(fmt, "{} (reason: {:?})", self, reason),
            _ => write!(fmt, "{}", self),
        }
    }
}
