Buffer typedefs raises parser exception

Uwe Schmitt:

Hi,

I got a problem with the following typedef

   ctypedef  np.ndarray[np.double_t, ndim=1, negative_indices=False, mode="c"] ndarray

results in

    Traceback (most recent call last):

        if base_type.name is None:
    AttributeError: 'CBufferAccessTypeNode' object has no attribute 'name'

Is this a bug ?}}}

Yes, it is. Ideally one should add this as a feature, but at least it should give a better error message.
