> VectorExtractRow relies on the fact that vector[i] and length[i] are
> consistent within the BytesColumnVector, otherwise it throws exception:

> There is a scenario when only vector[i] has been cleaned while reusing the
> column vector, and then this kind of exception can be thrown:
> the reproduction was made with
