[jira] [Commented] (ARROW-8999) [Python][C++] Non-deterministic segfault in "AMD64 MacOS 10.15 Python 3.7" build

    [ https://issues.apache.org/jira/browse/ARROW-8999?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17121531#comment-17121531 ] 

Yibo Cai commented on ARROW-8999:
---------------------------------

Looks like some hidden bugs like https://github.com/apache/arrow/pull/7123.
I met with same error once last week.
My patch https://github.com/apache/arrow/pull/7135 handles buffer directly, would double check if all boundary conditions are safe.
