            <title>[SERVER-41702] Copy Collection NamespaceString before yielding locks in AutoGetCollectionForRead</title>
                <link>https://jira.mongodb.org/browse/SERVER-41702</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;AutoGetCollectionForRead yields its locks &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2581b5d745009e17ac5a94ea7fe1e9a41b7905ed/src/mongo/db/db_raii.cpp#L172&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;, then tries to print a &lt;tt&gt;const NamespaceString&amp;amp; nss&lt;/tt&gt; &lt;a href=&quot;https://github.com/mongodb/mongo/blob/2581b5d745009e17ac5a94ea7fe1e9a41b7905ed/src/mongo/db/db_raii.cpp#L183&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;If the collection is dropped after the locks are yielded and before the line is printed, then it will result in an invalid access.&lt;/p&gt;

&lt;p&gt;We should copy the NamespaceString before yielding locks to print later on.&lt;/p&gt;</description>
