Right.  I reproduced this on my linux box.  This is an incompatibility
with how Stackless does away with the PyHeapTypeObject except as a
define for PyTypeObject.  If the initialisation in siplib.c is
corrected to match the way Stackless is doing this, then this crash
will go away and I expect PyQT built on a "corrected for Stackless"
sip will also work.  It would be good if someone could confirm that.

I do not have a fix for Stackless at this time.

Change the following in siplib.c:

static sipWrapperType sipWrapper_Type = {
    {
        {
            PyObject_HEAD_INIT(&sipWrapperType_Type)
            0,              /* ob_size */
            "sip.wrapper",          /* tp_name */
            sizeof (sipWrapper),        /* tp_basicsize */
            0,              /* tp_itemsize */
            (destructor)sipWrapper_dealloc, /* tp_dealloc */
            0,              /* tp_print */
            0,              /* tp_getattr */
            0,              /* tp_setattr */
            0,              /* tp_compare */
            0,              /* tp_repr */
            0,              /* tp_as_number */
            0,              /* tp_as_sequence */
            0,              /* tp_as_mapping */

            0,              /* tp_call */
            0,              /* tp_str */
            sipWrapper_getattro,        /* tp_getattro */
            sipWrapper_setattro,        /* tp_setattro */
            0,              /* tp_as_buffer */
            Py_TPFLAGS_DEFAULT | Py_TPFLAGS_BASETYPE |

            (traverseproc)sipWrapper_traverse,  /* tp_traverse */

            0,              /* tp_richcompare */
            0,              /* tp_weaklistoffset */
            0,              /* tp_iter */
            0,              /* tp_iternext */
            0,              /* tp_methods */
            0,              /* tp_members */
            0,              /* tp_getset */

            0,              /* tp_descr_set */
