[Boost-users] [uBLAS + Serialization] Is This Safe?

Hi all,

I found that uBLAS doesn't have Serialization support built in. So in my 
code, I do the following:
===== snip =====
class A
{
     typedef boost::numeric::ublas::c_vector<float, 3> container_t;
public:
     // Other member functions...
private:
     friend class boost::serialization::access;
     template <typename Archive>
     void serialize(Archive &ar, unsigned int version)
     {
         container_t::pointer data = data_.data();
         container_t::value_type (*p)[3] =
             reinterpret_cast<container_t::value_type (*)[3]>(data);
         ar & boost::serialization::make_nvp("data", *p);
     }
private:
     // The data field to be serialized
     container_t data_;
};
===== snip =====

While this code seems to be working on my machine, there is 
reinterpret_cast<> in place in order to grab the content of the vector, 
as you can see. So my question is: Is this way of performing 
serialization safe/ portable/ etc.?

Any idea?

Cheers,

Freddie
