Portable trait does not consider indirect types #598
Description
I was chasing an error from miri until I stumbled on #436 (comment) and with that flag it still panicked, but differently. Take out miri and it still panics. Huh.
thread 'tests::huh' panicked at /home/tv/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/rancor-0.1.0/src/lib.rs:648:9:
created a new `Panic` from: unaligned pointer: ptr 0x00007ffff00015f7 unaligned for alignment 8
#[cfg(test)]
mod tests {
use indexmap::IndexSet;
#[test]
fn huh() {
let mut orig: IndexSet<u64> = IndexSet::new();
orig.insert(1);
let bytes = rkyv::to_bytes::<rkyv::rancor::Panic>(&orig).unwrap();
let _archived = rkyv::access::<
rkyv::collections::swiss_table::index_set::ArchivedIndexSet<u64>,
rkyv::rancor::Panic,

.unwrap();

name = "huh"
version = "0.1.0"
edition = "2024"
[dependencies]
indexmap = "2.7.1"
rkyv = { version = "0.8.10", features = ["indexmap-2", "unaligned"] }Panics the same way with IndexMap too.
This should not be happening, for two reasons:
- I'm getting an
AlignedVecfrom rkyv::to_bytes, so alignment problems aren't my fault. - I'm asking for
unalignedfeature.
