no errors encountered even though `delay_span_bug` issued #107691

winterqt · 2023-02-05T15:27:05Z

The notable difference between this issue and others like it (#107684, #107678, #107686) are that this is happening in 1.67.0 (where the others have it in nightly), and in release mode (where at least one of them only happens in debug mode). Posting this as a separate ticket given these reasons, I hope that's okay.

Code

use rkyv::{
    with::{CopyOptimize, RefAsBox},
    Archive, Serialize,
};

#[derive(Archive, Serialize, Debug)]
pub struct Record<'a> {
    #[with(CopyOptimize, RefAsBox)]
    payload: &'a [u8],
}

(Tested with rkyv v0.7.39)

This only happens when building in release mode.

Error output

I just confirmed this is also fixed by #107688, but it would be nice to have a reduced test case for this one.
