As said, to my understanding,

1. zone_vector is modified *in-place*, you don't need to convert it back.

2. Instead, you have to allocate the numpy array big enough to hold *all*
   of the data

3. Blitz does not check array bounds

4. Writing out of array bounds does not necessarily result to a
   segmentation fault immediately, it can manifest later.

So, you should replace

	zone_vector = array(())

with

	zone_vector = zeros((size_of_zone_vector,))

Did you try this? If yes, does it fix the problem?
