`derive` Encode overflow

[ashWhiteHat]

The overflowed its stack error happens as following.

running 1 test

thread 'g1::tests::parity_codec_trait' has overflowed its stack
fatal runtime error: stack overflow
error: test failed, to rerun pass '--lib'

I inherit Encode to struct G1Affine.

#[derive(Copy, Clone, HexDebug)]
pub struct G1Affine {
    pub(crate) x: Fp,
    pub(crate) y: Fp,
    infinity: Choice,
}

impl Encode for G1Affine {}

The error happened when I executed encode methods.
encode

I would like to know what's happening 😥
Thank you!

Run with gdb and show the stack trace please.

I fixed with forking and derived.
Thank you!
