[jira] [Updated] (ARROW-12240) [Python] invalid-offsetof warning
[ https://issues.apache.org/jira/browse/ARROW-12240?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yibo Cai updated ARROW-12240:
-----------------------------
Description:
Same issue as https://issues.apache.org/jira/browse/ARROW-11299.
Found when building pyarrow on Macos M1. I don't think it's platform related.
No warning for clang-9, but apple clang-12 complains about it.
Error log:
{code:bash}
