Hi Daniel,

I can't see anything wrong. So, you should put in the old print statements 
where you allocate and delete (also indicate how much you allocated). Then 
we can see if you are indeed doing what you think you are doing. I can do 
that as well if you give me the stuff that compiles and create the 
appropriate shared library.
