//@ run-pass
// If a struct is packed and its last field has drop glue, then that
// field needs to be Sized (to allow it to be destroyed out-of-place).
//
// This is checked by the compiler during wfcheck. That check used
// to have problems with associated types in the last field - test
// that this doesn't ICE.
