New issue 1973: numpy crossproduct fails
https://bitbucket.org/pypy/pypy/issue/1973/numpy-crossproduct-fails
mike fc:
There's an issue with the np.cross() function with pypy - it fails with an
IndexError
e.g. np.cross(np.array([1,2,3]), np.array([4,5,6]))
Using latest pypy nightly, along with pypy-numpy latest checkout.
```
