            <title>[SERVER-83115] [CQF] SBE values leaked when parameterization enabled</title>
                <link>https://jira.mongodb.org/browse/SERVER-83115</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When we translate MatchExpressions to ABT with parameterization enabled, we construct SBE values for constants which are parameterized in order to get their type. However, in several cases, we forget to free this memory. Example &lt;a href=&quot;https://github.com/10gen/mongo/blob/00a866a0b86468da77df74454ae95e9a4e4317e0/src/mongo/db/pipeline/abt/match_expression_visitor.cpp#L597-L603&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;1&lt;/a&gt;, &lt;a href=&quot;https://github.com/10gen/mongo/blob/00a866a0b86468da77df74454ae95e9a4e4317e0/src/mongo/db/pipeline/abt/match_expression_visitor.cpp#L258-L278&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;2&lt;/a&gt;, etc.&lt;/p&gt;

&lt;p&gt;We should audit translation of ABT with parameterization to fix these and run an ASAN patch build with parameterization enabled.&lt;/p&gt;</description>
