[Python][C++][CI] test_s3_options crash on macOS

[pitrou]

Describe the bug, including details regarding any error messages, version, and platform.

test_s3_options has started crashing on macOS CI builds:
https://github.com/apache/arrow/actions/runs/20185836834/job/57955476278

The only significant difference with a previous successful build is probably that the AWS SDK was upgraded in Homebrew:

• before:

-- Found AWS SDK for C++, Version: 1.11.690, Install Root:/opt/homebrew, Platform Prefix:, Platform Dependent Libraries: pthread;curl
-- Components specified for AWSSDK: config;s3;transfer;identity-management;sts, application will be depending on libs: aws-cpp-sdk-config;aws-cpp-sdk-transfer;aws-cpp-sdk-identity-management;aws-cpp-sdk-cognito-identity;aws-cpp-sdk-sts;aws-cpp-sdk-s3;aws-cpp-sdk-core

• after:

-- Found AWS SDK for C++, Version: 1.11.705, Install Root:/opt/homebrew, Platform Prefix:, Platform Dependent Libraries: pthread;curl
-- Components specified for AWSSDK: config;s3;transfer;identity-management;sts, application will be depending on libs: aws-cpp-sdk-config;aws-cpp-sdk-transfer;aws-cpp-sdk-identity-management;aws-cpp-sdk-cognito-identity;aws-cpp-sdk-sts;aws-cpp-sdk-s3;aws-cpp-sdk-core

Component(s)

Continuous Integration, Python, C++

@AlenkaF @rok do any of you have some time to try and debug this? I can try an spin up a macOS on AWS to try and debug otherwise but I don't have a physical macOS to see if I can reproduce.

[rok]

Are we sure this is not related to AWS account?

Are we sure this is not related to AWS account?

It is currently segfaulting. It could be related to the AWS account, even though having an upgraded AWS library is more suspicious to me. No matter the cause we shouldn't segfault so if someone can reproduce and investigate the backtrace :)

[rok]

I can try to take a look tomorrow afternoon.

I will try to debug locally later today.

[AlenkaF]

test_s3_options passed with aws-sdk-cpp: stable 1.11.660. I am building Arrow with aws-sdk-cpp: stable 1.11.705 now and will add a backtrace in case I am able to reproduce the segfault.

[AlenkaF]

The test is passing locally with aws-sdk-cpp: stable 1.11.705
Python versions are different though (3.13 local vs 3.11 on the CI). I will try with Python 3.11 and see. Maybe I will come back with new info tomorrow.
