My rule of thumb when I create arrays in C code, is not to create arrays
in C code. Your problem is most probably that your memory does not get
freed, as it it not registered in Python's garbage collector. You could
learn how to do this (I don't know how). The other option is to use
numpy.empty to create an empty array, and pass it to your code that will
populate it. That way you don't have to deal with all this. It alos makes
your cod emore readable: no PyArrayObject* and co. in it.
My 2 cents,
