RE: Destructor problems

I've solved the problem!
A data member was declared to be an array [3][3] but it was filled as [5][5].
It's not clear to me what was wrong in the destructor (there should have been an out of index error ... I think) but filling it in the correct way everything works fine!

Bye...
