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