boost::multi_array resize doesn't work

I can't get boost::multi_array resizing to work. When I try it, it gives errors about std::_Copy_impl and the like. Here is the code

#include <boost/multi_array.hpp>

typedef boost::multi_array<int, 2> array_type;

class arrayclass{
public:
    arrayclass(array_type::extent_gen extents)
        : multiarray(extents[3][4]){
    }
    array_type multiarray;
};

int main(){
    array_type::extent_gen extents;
    arrayclass arraytest(extents);
    arraytest.multiarray.resize(extents[5][6]);
    return 0;
}

Edit: Here are the errors
