[jira] [Commented] (ARROW-10943) [Rust] Intermittent build failure in parquet encoding

["Andrew Lamb (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-10943?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17250519#comment-17250519 ] 

Andrew Lamb commented on ARROW-10943:
-------------------------------------

see https://github.com/apache/arrow/pull/8930#issuecomment-746661642 for some more context

I ran the arrow test suite this morning under valgrind and didn't see this before.

It started happening after https://github.com/apache/arrow/pull/8698 was merged (though that did not necessarily introduce the problem). [~gbowyer@fastmail.co.uk] did you see anything similar to this during development
