V575 The 'memcmp' function processes '0' elements. Inspect the 'third' argument. graphics3D matrix4.cpp 269

bool Matrix4::operator==(const Matrix4& other) const {
  if (memcmp(this, &other, sizeof(Matrix4) == 0)) {

A parenthesis put in a wrong place. This is how it should be: if (memcmp(this, &other, sizeof(Matrix4)) == 0) {

V575 The 'memcmp' function processes '0' elements. Inspect the 'third' argument. clist_modern modern_image_array.cpp 59

Arguments are mixed up. This is what should have been written here: memset(&iad->nodes[iad->nodes_allocated_size], 0, (size_grow - iad->nodes_allocated_size) * sizeof(IMAGE_ARRAY_DATA_NODE));
