            <title>[SERVER-44323] Investigate ASAN Static initialization order fiasco check</title>
                <link>https://jira.mongodb.org/browse/SERVER-44323</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-44290&quot; title=&quot;static order initialization fiasco in version.cpp&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-44290&quot;&gt;&lt;del&gt;SERVER-44290&lt;/del&gt;&lt;/a&gt; fixed a static initialization fiasco order issue that was detected on Windows un-optimized builds. ASAN offers a runtime flag &lt;tt&gt;check_initialization_order&lt;/tt&gt; that did not detect this latent issue.&lt;/p&gt;

&lt;p&gt;This ticket represents to work to determine to investigate if this is an issue that ASAN should have caught.&lt;/p&gt;</description>

                            <comment id="2570775" author="acm" created="Wed, 27 Nov 2019 20:02:35 +0000"  >&lt;p&gt;I built the parent commit of the fixing commit in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-44299&quot; title=&quot;Add tests for hashed shard key&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-44299&quot;&gt;&lt;del&gt;SERVER-44299&lt;/del&gt;&lt;/a&gt; on a VS2017 spawnhost, which should have allowed a reproduction. However, I do not observe a startup crash when running the built binary.&lt;/p&gt;

&lt;p&gt;Since there is not enough information recorded in the associated tickets to know what objects were involved in the observed initialization order fiasco, I&apos;m closing this ticket as incomplete: without knowing what objects were involved we can&apos;t make a determination if one of them was a windows-only object, which was my hypothesis for why ASAN couldn&apos;t find it.&lt;/p&gt;</comment>

&lt;p&gt;&lt;ins&gt;Windows, un-optimized build&lt;/ins&gt;&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;

		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;buildscripts\scons.py --dbg=on --opt=off&lt;/span&gt;&lt;/pre&gt;

		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;To repro, just start &lt;tt&gt;mongod.exe&lt;/tt&gt;.&lt;/p&gt;</comment>
