            <title>[SERVER-78680] TSAN suppression for WiredTiger may not work when WiredTiger calls into other libraries</title>
                <link>https://jira.mongodb.org/browse/SERVER-78680</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We have &lt;a href=&quot;https://github.com/mongodb/mongo/blob/8f376bd1c7e926fd4f96cf931f560880da5f9588/etc/tsan.suppressions#L8-L20&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;a TSAN suppression for WiredTiger&lt;/a&gt;, which as of &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-78018&quot; title=&quot;TSAN crashes on symbolization&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-78018&quot;&gt;&lt;del&gt;SERVER-78018&lt;/del&gt;&lt;/a&gt; is done by specifying &lt;tt&gt;called_from_lib:libwiredtiger.so&lt;/tt&gt;. However WT may call into another library (zstd for example) which then performs the write. Since the &lt;tt&gt;called_from_lib&lt;/tt&gt; suppression only cares about the library that actually performed the write (ignoring anything further up the stack), it does not get suppressed in this case.&lt;/p&gt;</description>

However, we suspect it may be complicated so let&apos;s be cautious about promising when it will be done. We&apos;ll assign this to &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=trevor.guidry%40mongodb.com&quot; class=&quot;user-hover&quot; rel=&quot;trevor.guidry@mongodb.com&quot;&gt;trevor.guidry@mongodb.com&lt;/a&gt;.&lt;/p&gt;</comment>

I think we should look for a better way to handle the crash and return to the original supression method.&lt;/p&gt;</comment>
