IndexError on ellipsis + slice

[Andreas Kloeckner]

Numpy:

>>> import numpy as np
>>> n = 2
>>> a = np.empty((2, n*6), dtype=np.float32)
>>> a[..., n*3:n*6]

Yes, we know about this. Note that it needs to be fixed inside the builtin _numpypy module - i.e. in the main PyPy repository.

This has just been fixed in PyPy default.
