 Reporter:  batavus              |       Owner:  wnbell     
     Type:  defect               |      Status:  new        
 Priority:  normal               |   Milestone:  Unscheduled
Component:  scipy.sparse.linalg  |     Version:  0.9.0      
 Keywords:  memory leak          |  
 The following program, run with scipy 0.9.0 on an up-to-date Debian
 testing, keeps eating more and more memory:

 import numpy, scipy.sparse.linalg
 a = scipy.sparse.csc_matrix(numpy.random.randn(20, 20))
 for i in xrange(500000):
     slv = scipy.sparse.linalg.factorized(a)
