[Numpy-discussion] memory not being freed

Hi
I'm having problems with garbage collection
I wrote an extension which creates an array
and returns it

foo() {
arr = (PyArrayObject *) PyArray_FromDims( .....
ret = Py_BuildValue("O", arr);
return ret;
}


but now if I do
while 1:
	a=foo()



memory is never free'd. I've even tried explicitly calling gc.collect and
adding del(a) after a=foo.

Is the problem that Py_BuildValue increases the reference count?

Mathew
