Old code relying on implementation detail, that elements[1] for the FFI_TYPE_COMPLEX was never read. But this type actually shares same assumption as the FFI_TYPE_STRUCT: the elements field is a NULL-terminated array of pointers to ffi_type objects. So far for primitive types - only complex types have this struct field as non-NULL (two element array).
