[SciPy-User] linalg.eigh hangs only after importing sparse module

The following simple code hangs only when sparse has been imported:

from scipy import sparse  # <<<<<<< BUG
import numpy as np
from scipy import linalg

N = 1000
X = np.random.random((N, N))
print X.mean()
v, Q = linalg.eigh(X)
print v.mean()

Do you think this may be related to other arpack/umfpack/etc. known failures ?

Please let us know how can we help fix this issue.

Thanks for your help.
