            <title>[SERVER-50004] Coverity analysis defect 114295: Bad bit shift operation</title>
                <link>https://jira.mongodb.org/browse/SERVER-50004</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Bad bit shift operation&lt;/p&gt;

&lt;p&gt; The operation may have an undefined behavior or yield an unexpected result. A bit shift operation has a shift amount which is too large or has a negative value.&lt;br/&gt;
/src/mongo/db/storage/key_string.cpp:693: BAD_SHIFT 114295 Function call &quot;mongo::countLeadingZeros64(integerPart &amp;lt;&amp;lt; 1)&quot; may return 64.&lt;br/&gt;
/src/mongo/db/storage/key_string.cpp:693: BAD_SHIFT 114295 Assigning: &quot;fractionalBytes&quot; = &quot;mongo::countLeadingZeros64(integerPart &amp;lt;&amp;lt; 1) / 8&quot;. The value of &quot;fractionalBytes&quot; is now 8.&lt;br/&gt;
/src/mongo/db/storage/key_string.cpp:707: BAD_SHIFT 114295 In expression &quot;integerPart + 1UL &amp;lt;&amp;lt; fractionalBytes * 8UL&quot;, left shifting by more than 63 bits has undefined behavior.  The shift amount, &quot;fractionalBytes * 8UL&quot;, is 64.&lt;/p&gt;</description>
