Try this:

temp = [ TEMPORARY(*self.foo),next_array ]
ptr_free,self.foo
self.free = ptr_new(temp,/NO_COPY)

When you are creating the new pointer you are duplicating memory.
The same occurs when you are retrieving the content of *self.foo. Use
the function TEMPORARY and the keyword NO_COPY, your code will be more
efficient.

Cheers,
