of underlying FEdges introduced by chaining operations. The material of a smooth FEdge is identified by the material index of the FEdge and the array of materials in the SShape to which the first SVertex (i.e., vertexA) of the FEdge belong. The present fix makes sure that the material index refers to the intended array of materials, to avoid inconsistent reference and out-of-index errors that lead to a crash.
