12454	multi_array: operator= does not resize array	martin.koerner@…	Ronald Garcia	"Hello,

the copy operator does not resize the array in contrast to the copy constructor, which does. That is a pitfall.

In case of a multi_array_ref the size cannot be changed, but for a multi_array it can and it also should change the size.

#include <boost/multi_array.hpp>

int main() {

  boost::multi_array<double, 2> a(boost::extents[3][4]);
  boost::multi_array<double, 2> b = a; // ok
  boost::multi_array<double, 2> c; // has size [0][0]
  c = a; // fails

  return 0;
