I will raise an issue in NumPy. It might better if we could tell which part of our code causes this bug. (And if we can avoid it within our code, it might be much quicker) Do you have any idea?

I confirmed + indexing by a Variable already causes this bug + only simple subclassing common.AbstractArray and utils.NdimSizeLenMixin does not cause this.

I suspect something related to Variable interpretation could trigger it.
