Looking at the corresponding test:

    def check_integer(self):
        from scipy import stats
        a = stats.randint.rvs(1,20,size=(3,4))
        fname = tempfile.mktemp('.dat')
        io.write_array(fname,a)
        b = io.read_array(fname,atype=N.Int)
        assert_array_equal(a,b)
        os.remove(fname)

and executing this line by line shows the error for
  b = io.read_array(fname,atype=N.Int)

Doing
  b = io.read_array(fname)
reads in the array, but it gives floats.

However,
  b = io.read_array(fname,atype=N.Int32)
works.

If this is the intended behaviour (also on 32Bit),
the unit test should be changed accordingly...

Best, Arnd
