You can get the version of scipy_core just before the fix that Travis
applied:

  svn co -r 1488 http://svn.scipy.org/svn/scipy_core/trunk

The fix:

  http://projects.scipy.org/scipy/scipy_core/changeset/1489
  http://projects.scipy.org/scipy/scipy_core/changeset/1490

Here's some code that eats up memory with rev1488, but not with the HEAD:

"""
import scipy

a = scipy.arange(10)
for i in xrange(10000000):
    x = a[5]
"""
