[jira] [Commented] (ARROW-11267) [Rust]: Comparison of list arrays with differing offsets fails

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

    [ https://issues.apache.org/jira/browse/ARROW-11267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17268231#comment-17268231 ] 

Andrew Lamb commented on ARROW-11267:
-------------------------------------

When I tested on https://github.com/apache/arrow/pull/9211/files -- this test case still fails (aka https://github.com/apache/arrow/pull/9211 does not seem to fix it)

> Found this while reviewing the fix for ARROW-11239. The reason for the failure seems to be related to the combining of null bitmaps of parent/child data. When I changed `create_list_array` to not include null buffers the test passes.
