[jira] [Commented] (ARROW-16873) [Python] test_debug_memory_pool_disabled segfaulting on MacOS CI

["Kouhei Sutou (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-16873?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17557182#comment-17557182 ] 

Kouhei Sutou commented on ARROW-16873:
--------------------------------------

This may be related to ARROW-16717.
System memory pool wasn't system {{malloc()}} before ARROW-16717. jemalloc was used since ARROW-16717.
It might change the behavior.

> 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.
