Arch Linux build fails since 0.27.1 with Rust 1.67.1

[hashworks]

The build of the Arch Linux vector package fails since 0.27.1. I'm not sure if it's caused by 0.27.1 or some other dependency update.

This is the error I'm getting:

error: internal compiler error: no errors encountered even though `delay_span_bug` issued

error: internal compiler error: broken MIR in Item(WithOptConstParam { did: DefId(0:2573 ~ vector_buffers[92e1]::variants::disk_v2::record::_::{impl#0}::resolve), const_param_did: None }) (after phase change to runtime-optimized) at bb4[53]:
                                Field projection `(*_4).field[3]` specified type `rkyv::boxed::ArchivedBox<[u8]>`, but actual type is `<rkyv::with::With<rkyv::with::With<&[u8], rkyv::with::RefAsBox>, rkyv::with::CopyOptimize> as rkyv::Archive>::Archived`
  --> lib/vector-buffers/src/variants/disk_v2/record.rs:46:10

This is the full build log.

This is the build script I'm using. The prepare() and build() functions run in order. Basically it's just this:

cargo fetch --locked
cargo build \
        --frozen \
        --release \
        --locked \
        --target x86_64-unknown-linux-gnu

The following (build-) dependencies are provided:

• gcc-libs 12.2.1
• zlib 1.2.13
• cargo / rust 1.67.1
• protobuf 21.12
• python 3.10.9
• perl 5.36.0
• cmake 3.25.2

Any ideas?

This is a known issue with rustc 1.67. I have a draft PR that is running into the same issue.

To add to this, if you want to use the same version of Rust we distribute Vector with you can use the rust-toolchain.toml file included in the repository.

Alright, switched to rustup.
