            <title>[GODRIVER-2157] Detect bit alignment issues when using &quot;sync/atomic&quot; to access struct fields</title>
                <link>https://jira.mongodb.org/browse/GODRIVER-2157</link>
                <project id="14289" key="GODRIVER">Go Driver</project>
                    <description>&lt;p&gt;Find a way to detect runtime errors like&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;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&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;panic: unaligned 64-bit atomic operation [recovered]&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;during a CI run. Those errors can happen when you run the &lt;em&gt;mongo-go-driver&lt;/em&gt; on certain 32-bit architectures (e.g. some 32-bit ARM platforms). Some static analysis tools, like `go vet`, may provide a checker for 64-bit alignment atomically-accessed struct fields.&lt;/p&gt;
