[Pkg-rust-maintainers] Bug#1099528: rust-zune-jpeg executes avx code during the build resulting in SIGILL: illegal instruction

Tue Mar 4 14:39:07 GMT 2025

Source: rust-zune-jpeg
Version: 0.4.14-1
Severity: minor

Hi,

I noticed that the build of rust-zune-jpeg fails on reproduce.debian.net
using a Intel Xeon X5690 but succeeds on my system with a i7-8565U:

https://reproduce.debian.net/amd64/#librust-zune-jpeg-dev

The relevant log is:

process didn't exit successfully: `CARGO=/usr/bin/cargo CARGO_MANIFEST_DIR=/build/reproducible-path/rust-zune-jpeg-0.4.14 CARGO_MANIFEST_PATH=/build/reproducible-path/rust-zune-jpeg-0.4.14/Cargo.toml CARGO_PKG_AUTHORS='caleb <etemesicaleb at gmail.com>' CARGO_PKG_DESCRIPTION='A fast, correct and safe jpeg decoder' CARGO_PKG_HOMEPAGE='' CARGO_PKG_LICENSE='MIT OR Apache-2.0 OR Zlib' CARGO_PKG_LICENSE_FILE='' CARGO_PKG_NAME=zune-jpeg CARGO_PKG_README=README.md CARGO_PKG_REPOSITORY='https://github.com/etemesi254/zune-image/tree/dev/crates/zune-jpeg' CARGO_PKG_RUST_VERSION='' CARGO_PKG_VERSION=0.4.14 CARGO_PKG_VERSION_MAJOR=0 CARGO_PKG_VERSION_MINOR=4 CARGO_PKG_VERSION_PATCH=14 CARGO_PKG_VERSION_PRE='' LD_LIBRARY_PATH='/build/reproducible-path/rust-zune-jpeg-0.4.14/target/x86_64-unknown-linux-gnu/debug/deps:/build/reproducible-path/rust-zune-jpeg-0.4.14/target/x86_64-unknown-linux-gnu/debug:/usr/lib/rustlib/x86_64-unknown-linux-gnu/lib' /build/reproducible-path/rust-zune-jpeg-0.4.14/target/x86_64-unknown-linux-gnu/debug/deps/zune_jpeg-9a5a94aed6dbf985` (signal: 4, SIGILL: illegal instruction)

Attaching gdb gives:

So it is using avx which is not in the Debian baseline:

As far as I can see the executable is not shipped in the binary package
and we can use a different machine for reproduce.d.n so setting to
minor.
