reference count problems

Hi
I'm running a 64 bit Python 2.5 on an x86 with Solaris. I have a 
function I call over 2^32 times and eventually I run out of memory.

The function is
def make_B(deltadates):
    numcols=deltadates.shape[0]
    B=numpy.zeros((numcols,numcols))
    for ind in range(0,numcols): #comment out this loop and all is good
        B[ind,0:numcols] = deltadates[0:numcols]
    return B


If I comment out the loop lines, my memory is okay. I'm guessing that a 
reference is being added to "deltadates" and that the reference count is 
going above 2^32 and reseting. Anybody have any ideas about how I can 
cure this? Is Numpy increasing the reference count here?

Mathew
