---------------------------------------+------------------------------------
 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.
