View dot multiplication causing runtime error

[Heavy-Sauria]

The following example causing runtime error:

#ifndef __TESTCPP__
#define __TESTCPP__

#include <iostream>
#include <xtensor/xarray.hpp>
#include <xtensor/xfixed.hpp>
#include <xtensor/xio.hpp>
#include <xtensor/xtensor.hpp>
#include <xtensor/xview.hpp>
#include <xtensor/xindex_view.hpp>

#include "xtensor-blas/xlinalg.hpp"

int main()
{
    xt::xtensor_fixed<double, xt::xshape<4, 4> > c = xt::linspace<double>(1.0, 16, 16);
    std::cout << c << std::endl
              << std::endl;
    xt::filter(c, c > 5) = 0;
    std::cout << c << std::endl
              << std::endl;

    auto v1 = xt::view(c, xt::range(0, 2), xt::range(0, 2));

    std::cout << v1 << std::endl
              << std::endl;

    v1 = xt::linalg::dot(v1, v1);
    std::cout << c << std::endl;
}

#endif

Result:

{{  1.,   2.,   3.,   4.},
 {  5.,   6.,   7.,   8.},
 {  9.,  10.,  11.,  12.},
 { 13.,  14.,  15.,  16.}}

{{ 1.,  2.,  3.,  4.},
 { 5.,  0.,  0.,  0.},
 { 0.,  0.,  0.,  0.},
 { 0.,  0.,  0.,  0.}}

{{ 1.,  2.},
 { 5.,  0.}}
