This suggests another possible workaround:
cdef extern from "Python.h":
int PyObject_GenericDelAttr "PyObject_GenericSetAttr"

Hmmm
changing the include definition to:

int PyObject_GenericSetAttr(PyObject*, PyObject*, PyObject*) except -1
Seems to solve the problem, with the inconvenience of needing to explicitly
cast to before calling it. However, the objects are no longer
incref'd before c
I should mention, that these PyObject_Generic* functions are being used from
with __getattribute__, __setattr__, and __delattr__ methods. I should have
added that context in the begining.

The problem with delattr (and thus PyObject_DelAttr) arises when you define
a __delattr__ method on your class. There is not easy way to then call back
into the "normal" python delattr semantics, except by doing
object.__delattr__ (which is not optimized by Cython).
Futher, calling PyObject_Generi
