So it turns out that ndarray.data supports assignment at the Python level, and what it does is just assign to the ->data field of the ndarray object: https://github.com/numpy/numpy/blob/master/numpy/core/src/multiarray/getset.c#L325
This kind of assignment been deprecated at the C level since 1.7, and is totally unsafe -- if there are any views pointing to the array when this happens, then they'll be left pointing off into unallocated memory. E.g.: a = np.arange(10) b = np.linspace(0, 1, 10) c = a.view() a.data = b.data # Now c points into free'd memory Can we deprecate or just remove this?
