> Does Numpy correctly call PyType_Ready()?

As far as I can tell, it does:


#define DUAL_INHERIT(child, parent1, parent2)                           \
    Py##child##ArrType_Type.tp_base = &Py##parent2##ArrType_Type;       \
    Py##child##ArrType_Type.tp_bases =                                  \
        Py_BuildValue("(OO)", &Py##parent2##ArrType_Type,               \
                      &Py##parent1##_Type);                             \
    if (PyType_Ready(&Py##child##ArrType_Type) < 0) {                   \
        PyErr_Print();                                                  \
        PyErr_Format(PyExc_SystemError,                                 \
                     "could not initialize Py%sArrType_Type",           \
                     #child);                                           \
        return -1;                                                      \
    }                                                                   \
    Py##child##ArrType_Type.tp_hash = Py##parent1##_Type.tp_hash;
    ...
    DUAL_INHERIT(Int, Int, SignedInteger);

Could it be the multiple inheritance that causes the problem here?
