Hi,
I found what I think is a bug in boost/multi_array.hpp. Perhaps some
of you can explain what is wrong. Look at the code below. When
executed you get the following error:
multi_array_ref.hpp:487: failed assertion
`std::equal(other.shape(),other.shape()+this->num_dimensions(),
this->shape())'
This is caused by the line
x.resize(extents[n+1][3]);
This seems to be by design.  Multiarray doesn't have normal assignment 
semantics.

#include "boost/multi_array.hpp"
#include <vector>

using boost::multi_array;
using boost::extents;
using std::vector;

int main(void) {

    multi_array<int, 1> x(boost::extents[2]), y;
    y = x;
}

In Christ,
