[Numpy-discussion] memory leak using numpy and cvxopt

Hi all,

I am hitting a memory leak with the combination of numpy and cvxopt.matrix. As 
I am not where it occurs, I am cross posting.

On my machine (Fedora 13, x86_64) this example quickly eats up all my memory.

from cvxopt import matrix
import numpy as np

N = 2000

X = np.ones((N, N))
Y = matrix(0.0, (N, N))

while True:
    Y[:N, :N] = X

I don't hit the leak if copy blocks of 1-d arrays.
