Boost.MultiArray: Resizing bug if the index is not 0-based

[avhacker@…]

I find that a boost::multi_array will crash when calling to resize() with non 0-based indexes. The implementation seems have problem if the array is not 0-based.

Please see the following code:

#include <boost/multi_array.hpp>
#include <boost/array.hpp>

int main(int,char*[])
{
	typedef boost::multi_array<int, 2> marray;
	marray A(boost::extents[5][5]);

	boost::array<marray::index, 2> bases;
	bases[0] = 2;
	bases[1] = 3;
	A.reindex(bases);

// 	bases[0] = 0;
// 	bases[1] = 0;
// 	A.reindex(bases);

	A.resize(boost::extents[7][7]);
	bases[0] = 2;
	bases[1] = 3;
	A.reindex(bases);

	return 0;
}

The above program will get crash unless you uncomment the 3 lines that re-index bases to 0.

This code passes for me with GCC 4.1.2, even under Valgrind.
