You don't need to clear the original array but it should be harmless.

Is this a 32-bit platform? If so, the reason may be the conservative GC 
that dmd uses. What happens is, unrelated 32-bit values in other parts 
of the program may look like pointers into the allocated space and the 
GC thinks that they are still in use.
