cascaded list unpacking into typed targets crashes

[robertwb]

See extended_unpacking_T409 test:

  long __pyx_t_2;
  long __pyx_t_3;
  /*
 *     a, *b, c = d = e = [1,2]             # <<<<<<<<<<<<<<
 */
  __pyx_t_1 = PyList_New(2); if /* ... */
  __Pyx_GOTREF(((PyObject *)__pyx_t_1));
  __Pyx_INCREF(((PyObject *)1));
  PyList_SET_ITEM(__pyx_t_1, 0, ((PyObject *)1));
  __Pyx_GIVEREF(((PyObject *)1));
  __Pyx_INCREF(((PyObject *)2));
  PyList_SET_ITEM(__pyx_t_1, 1, ((PyObject *)2));
  __Pyx_GIVEREF(((PyObject *)2));
  __pyx_t_2 = 1;
  __pyx_t_3 = 2;
