multi_array::resize index error

[wasti.redl@…]

multi_array::resize wants to copy the old data to the new. However, it confuses the old and new arrays when calculating the indices for the subviews. As a result, creating the view asserts.

Minimal crashing example:

#include <boost/multi_array.hpp>

int main() {

typedef boost::multi_array<int, 1> ar_t; typedef ar_t::extent_range range; ar_t ar; ar.resize(boost::extents[range(-3, 3)]);

}

The attached patched solves the problem.

Patch that solves the bug.
