Calling dispose() on a record with a dynamic array field will free the  
array (and recursively finalize all its elements) as long as the  
pointer on which you call it is correctly typed in the source code.  
The fact that you still get memory leaks after everything you are  
doing suggests that something else is wrong in your program.
