You're right Tim but I was assuming msvc compiler was doing the 
correction automaticaly and I think that is actually what it does. Gcc 
doesn't and then came the pb.
Even with no warnings about const reference type, msvc produced a code 
that is fully functionnal and stable.

I agree anyway that we must pay attention to stay in the correct 
programming way of C++.
