My cargo build is failing with a panic, directing me here to post information.

I tried this code:

guid.rs:

pub type GuidPrefix = [u8; 12];

#[derive(Default, Debug, PartialEq, Copy, Clone)]
pub struct Guid {
    pub guid_prefix: GuidPrefix,
    pub entity_id: EntityId
}


impl Guid {
    pub fn new() -> Self {
        Guid {
            guid_prefix: [0; 12],
            entity_id: EntityId {
                entity_key: [0; 3],
                entity_kind: EntityKind::UserUnknown
            }
        }
    }
}

entity_id.rs:

#[derive(Default, Debug, PartialEq, Copy, Clone, Deserialize, Serialize)]
pub struct EntityId {
    pub entity_key: [u8; 3],
    pub entity_kind: EntityKind,
}

I expected to see this happen: no panics

Instead, this happened: panic

I think this could be #37788, in which case it should be fixed by #37793.

I think I'm getting the same error. The fix was merged 15 minutes ago. Is there a way to get this working or do I need to wait for the nightly build? (Is it actually built every night?)

This is my code:

#![feature(proc_macro)]

#[macro_use]
extern crate serde_derive;

extern crate serde;
extern crate serde_json;
extern crate rustc_serialize;

extern crate image;

use std::io::BufRead;

#[derive(Debug, PartialEq, Serialize, Deserialize)]
enum Action {
    Undo,
    Redo,
    Crop {x: u32, y: u32, width: u32, height: u32},
    FlipHorizontal,
    FlipVertical,
    Resize {width: u32, height: u32},
}

This is the full error with stacktrace:

@jseyfried I'm still getting the same error in the latest nightly. Is this a separate issue? Did that not get put into the latest nightly?

With the same code as in my comment above:

@jseyfried Any idea when this will make it into nightly? Still getting this error on the latest one.

@sunjay This is fixed in the latest nightly (2016-11-19), so there should be no ICE.

The earlier errors, like a type named `Action` has already been defined in this module, are from using and old version of serde_derive -- only 0.8.18 works with latest nighties. I believe removing Cargo.lock and rebuilding will update serde_derive to the lastest version.

I just tested the code from #37795 (comment) in a fresh cargo project and it compiles successfully.

@jseyfried Thank you so much! I ran cargo update and everything works with the latest serde_derive as well as the latest nightly.
