problems with pointcollection and EnumVertex

Hey,

I am trying to add a pointcollection into a feature class using the IEnumVertex2 interface. When I try to instantiate the enumVertex, I get the loader lock error. Here are some code snippets:

                IMultipoint pMultiPoint;
                pMultiPoint = new MultipointClass();
                IPointCollection5 pPointCollection;
                pPointCollection = (IPointCollection5)pMultiPoint;

               //I add some points to the point collection

                    IGeometryBridge2 gBridge = new GeometryEnvironmentClass();
                    gBridge.AddPoints(pPointCollection, ref pPoint);

// it dies here with a loader lock error -- the pIEnumVertex is null.
                    IEnumVertex2 pIEnumVertex = (IEnumVertex2)pPointCollection.EnumVertices;
                    IPoint queryVertex = new PointClass();
                    int pIndex;
                    int vertIndex;
                    IPoint outVertex;
                    pIEnumVertex.Next(out outVertex, out pIndex, out vertIndex);

Any ideas what is going wrong? What is the best way to place a point collection into a feature class?

Thanks, Chris
