multi_array: operator= does not resize array

[martin.koerner@…]

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;

}
