Actually ubsan did also report that issue about `G1CardSetArray`, it has been added as comment to this issue (https://bugs.openjdk.org/browse/JDK-8331920?focusedId=14671937&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14671937). Still I think it is fine to create an extra CR.
