                            <comment id="5071614" author="JIRAUSER1271286" created="Wed, 21 Dec 2022 23:05:00 +0000"  >&lt;p&gt;For context, one of the issues found previously: &lt;a href=&quot;https://github.com/10gen/mongo/pull/7821#discussion_r987266879&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/pull/7821#discussion_r987266879&lt;/a&gt;&#160;&lt;/p&gt;

&lt;p&gt;The fuzzer has found bugs of this sort in the past (i.e. different column scan plans hashing to the same plan cache key), so we likely already have decent coverage on this.&#160;&lt;/p&gt;

&lt;p&gt;I also created find/aggregate overrides that replace match expression leaf values with random constants of various types, run the modified query twice to cache it, then run the original and return its results. I ran the core_column_store_indexes and aggregation_column_store_index_passthrough suites several times with this override (also confirmed that the overrides would have brought out the bug linked above) - no new issues were hit.&lt;/p&gt;</comment>
