--------------------------------

             Summary: [Python] test_debug_memory_pool_disabled segfaulting on MacOS CI
                 Key: ARROW-16873
                 URL: https://issues.apache.org/jira/browse/ARROW-16873
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: David Li


Observed on master and many PRs, example: https://github.com/apache/arrow/runs/6991997196?check_suite_focus=true

From a quick read, it's likely just that the stderr isn't necessarily empty as the test expects.
