<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">Coverity flagged a spot where the _Objects_Information_table may be used with an index that is too large. However, this method is only used during initialization and the API and class fields passed should be able to be trusted. In light of this, the decision was made to add an _Assert which will let Coverity Scan know it is accounted for.</p>
