                    <description>&lt;p&gt;We currently &lt;a href=&quot;https://github.com/mongodb/mongo/blob/70c9397a814fc95406feaf8afa7028ce0a2473ee/src/mongo/db/ops/write_ops_exec.cpp#L1176-L1183&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;use a reference to a &lt;tt&gt;TransactionParticipant&lt;/tt&gt; that is on the stack inside of a storage transaction rollback handler&lt;/a&gt;. However, due to C++ destruction ordering, when we leave the frame this variable goes out of scope before the &lt;tt&gt;WriteUnitOfWork&lt;/tt&gt; whose destructor causes the handler to run.&lt;/p&gt;</description>
