Description

Our team has been using buildx to build multi-arch fluent-bit image long time ago. However, the build for ARM64 image on debian:bullseye started to failing two months ago with following error:

#39 249.8 ===============================================================================
#39 250.9 [ 27%] Performing build step for 'jemalloc'
#39 251.5 gcc: internal compiler error: Segmentation fault signal terminated program cc1
#39 251.5 Please submit a full bug report,
#39 251.5 with preprocessed source if appropriate.

After a lot of troubleshooting steps, we noticed there is some compatibility issue between QEMU and Debian kernel 5.10.0-33-cloud-amd64/5.10.0-33-debian-amd64. We used following approach to setup QEMU for buildx:

sudo docker run --privileged --rm tonistiigi/binfmt:qemu --install all
sudo docker buildx create --name builder --use
sudo docker buildx inspect --bootstrap

And we tried different version of QEMU including 6.2, 7.0, 8.2 and 9.2.1 (latest) but none of them works with this kernel. As soon as I downgrade the kernel version to 5.10.0-32-cloud-amd64, the build starts to work again.

Since changing kernel version, native build and cross-compiling are not options for our CI//CD pipeline, we are wondering how can we move forward to address this problem.

Expected behaviour

The build succeeds.

Actual behaviour

The build failed with internal compiler error.

Research direction

Start with the linked fluent-bit Dockerfile and the provided docker buildx build --platform=linux/arm64 command, then reproduce the failure using the listed buildx, BuildKit, QEMU, Docker, and Debian kernel versions. Compare the working 5.10.0-32 kernel with 5.10.0-33 and verify whether the failure is attributable to buildx or an external QEMU/kernel interaction; done means a confirmed cause or a documented, actionable compatibility conclusion.
