[ublas] addition of sparse_matrix: compilation problem

Hello,

I've got a problem compiling the next example:

#include <iostream>
#include <boost/numeric/ublas/matrix_sparse.hpp>
#include <boost/numeric/ublas/storage.hpp>
#include <boost/numeric/ublas/io.hpp>

using namespace boost::numeric::ublas;

int main(void)
{
  sparse_matrix<unsigned> *m, *n, *r;
  m = new sparse_matrix<unsigned>(3,3);
  n = new sparse_matrix<unsigned>(3,3);
  r = new sparse_matrix<unsigned>(3,3);

  for (unsigned i = 0; i < 3; ++i)
    for (unsigned j = 0; j < 3; ++j)
      (*m)(i,j) = i+j;

  *n = *m; //no problems in assignment
  *r = *m + *n; //this gives problems!!

  std::cout << *r << std::endl;

  return 0;
}

This example compiles on a Pentium4 with gcc 3.2.3, but not on an Opteron with
gcc 4.0.0. When the line with addition of the two matrices is commented out, the
example compiles.

I'm not sure if it's a 64-bit problem (P4 vs Opteron) or a gcc version problem.
Anybody got any ideas? The errors I get are listed below:
