Interesting. We have in that function:
v = [(mn + j*step, mn + (j+1)*step) for j in range(bins)]
and then a few lines later:
cdef Py_ssize_t j
That's probably a bad idea. The cdef line should be above that first line.
There's a patch up at http://trac.sagemath.org/sage_trac/ticket/6824
that fixes this. Reviewers for this simple fix are welcome!

I looked at the sources briefly and nothing looked out of the ordinary.
I'm wondering if somehow the new Cython was not installed at this
point in the build process, so somehow an old numpy pxd file was being
used. I don't know.

A new tarball worked for me. I didn't upgrade. But then again, I'm not
on a 64-bit system.
Thanks,
