Intermittent segmentation faults on Ubuntu 24.04 ARM, multiple Actions and binaries

[bbasata]

Description

Original report: hashicorp/setup-terraform#459

I'm investigating this report of segmentation faults on hashicorp/setup-terraform runs on ubuntu-24.04-arm. So I constructed a test repo that was reliably reproducing a ~15% fault rate.

In recent runs of the test repo, I am now seeing errors in actions/checkout (exit code 139) that were not occurring before. On the surface, exit code 139 matches Docker's exit code for a segmentation fault.

Runner image provisioner, for successful and failed runs: 2.0.422.1

The test repo:

GitHub repo (arm branch): bbasata/setup-terraform-issue-459:arm
Workflow runs: https://github.com/bbasata/setup-terraform-issue-459/actions/workflows/terraform.yml

Is it regression?

Yes

Expected behavior

Successful workflow runs

Actual behavior

Intermittent segmentation faults that fail the workflow run

Repro steps

1. Fork https://github.com/bbasata/setup-terraform-issue-459
2. Run the Terraform workflow with branch arm -- it runs 30 small jobs
3. Expect all 30 jobs to succeed

Hi @bbasata, Thank you for bringing this issue to our attention. We are looking into this issue and will update you on this issue after investigating.

I am seeing flaky behavior on ubuntu-24.04-arm

• checkout fails (as reported here)
• also 3154 Segmentation fault (core dumped) npm ci

Re-running the failing workflow will sometimes then run successfully.
https://www.githubstatus.com/ shows no outage at this time.

Does anyone have a simple repro for this I can use to investigate?

You can fork https://github.com/cypress-io/cypress-docker-images and run the workflow https://github.com/cypress-io/cypress-docker-images/actions/workflows/example-tests.yml manually.

The tests are randomly failing.

Thanks for looking at this! I don't really want to disable ubuntu-24.04-arm if I can help it, so it would be great to fix it!
