Investigate docker build issue on linux/arm64 platform

[masih]

Initially observed in #834 but it is unrelated to the changes in that PR: confirmed by re-running the docker build on latest commit of main here. The issue:

> [linux/arm64 build 6/6] RUN go build -o /go/bin/f3 ./cmd/f3:
87.02 runtime/cgo: gcc: signal: segmentation fault (core dumped)
------
WARNING: No output specified with docker-container driver. Build result will only remain in the build cache. To push result image into registry use --push or to load image into docker use --load
Dockerfile:9
--------------------
   7 |     
   8 |     COPY . .
   9 | >>> RUN go build -o /go/bin/f3 ./cmd/f3
  10 |     
  11 |     FROM gcr.io/distroless/cc
--------------------
ERROR: failed to solve: process "/dev/.buildkit_qemu_emulator /bin/sh -c go build -o /go/bin/f3 ./cmd/f3" did not complete successfully: exit code: 1

Why has it started failing now?

Because go-f3 container build is not reproducible:

• the dockerfile uses latest tags for the build and base images.
• the GitHub actions use a soft version for the build setup.

Change at any of the above layers could have caused the issue, e.g. gcc linker upgrade.
Also, yesterday GitHub Actions was having a bad day with a flurry of errors specifically in docker build jobs which may be related.

Building multi-platform containers locally (using podman) passes for me with no issues.

Unblocking the merge of that PR by capturing this issue to investigate the problem separately.

Builds now started passing on main without any updates to docker build process. Also see: docker/build-push-action#1309

IMO it looks like the VM is running out of RAM and causing some weird behavior. It looks like I've found a workaround, as I've commented in my issue:

jobs:

  build:
    runs-on: ubuntu-22.04

Please try like that and let me know if it helps. :)

Thank you @FacuM, I'll give that a shot 👍

@FacuM In our case using the ubuntu-22.04 runner image made no difference. See: https://github.com/filecoin-project/go-f3/actions/runs/13007480659/job/36277473006?pr=855

With QEMU setup it still fails: https://github.com/filecoin-project/go-f3/actions/runs/13013844154/job/36297943821

Update using qemu v8 works.
