Same leak here using Numeric 24.2 and numpy 1.0.1 on Linux.

Also fine. And for the record using the intermediate list also works for me:
import sys, numpy, Numeric
na = numpy.array([0.0])
na_list = list(na)
for i in xrange(1000000):
foo = Numeric.array(na_list, Numeric.Float)
print sys.getrefcount(na)
