[Pysparse-users] Memory leak

[Nicola C. <nc...@in...>]

Hello,
I found a memory leak using pysparse if I create and fill an array 
several times. At each step the memory increases. I attached an example 
script that reproduces the problem.
Thanks.

Cheers.

Nicola


from pysparse import spmatrix

def do():
     A = spmatrix.ll_mat(256**2, 256**2)
     for x in range(256):
         for y in range(256):
             k = y*256+x
             A[k,k] = 1
     return A

if __name__ == '__main__':
     for i in range(1024):
         b= do()

Thanks for this and for the example. I'll try and look into it at some
point and get back to you.
