[Numpy-discussion] Strange PyArray_FromObject() behavior

I have a user who is reporting tests that are failing on his platform. I have not been able to reproduce the error on my system, but working with him, we have isolated the problem to unexpected results when PyArray_FromObject() is called. Here is the chain of events:
In python, an integer is calculated. Specifically, it is
len(result.errors) + len(result.failures)
where result is a unit test result object from the unittest module. I had him verify that this value was in fact a python integer. In my extension module, this PyObject gets passed to the PyArray_FromObject() function in a routine that comes from numpy.i. What I expect, and what I typically get, is a numpy scalar array of type C long. I had my user print the result using PyObject_Print() and what he got was
I am stuck as to why this might be happening. Any ideas?
