Again thank you all who helped me in this .

It was secondary error.

This was the problem, so it wasn't shot in the dark at all.
The problem was that my classes have the following class members :
shared_ptr<const T> , vector<const T>, vector<shared_ptr<const T>> and many
others  that have const inside them. I can not remove const from these,
altghough  I wish :)
I was casting const away (http://tinyurl.com/yae5stv ) for all this members
only at the point of loading, for example in many cases I was saving
vector<const T> and loading vector<T>. Now I added const cast at the point
of saving too, so saving and loading is symmetric. It seems it works Ok now,
and I hope this is the right way to solve the problem.
