Yes, the results must be the same, but only if there isn't another bug. 
I'm completly sure about z-coord interpolation cos I use it daily. 
However, since I don't use it with attributes values I don't know if it 
works properly well. It should do so because the interpolation functions 
are the same in both cases.

Obviously it works well to me, otherwise, I wouldn't have done the update 
to cvs. However, till you don't do this last test I can't be sure. That 
was what I wanted to mean, some caution. Sorry if I created some doubts. 
It was no my intention.
