Well depending on the size of the array, it may not lead to that since the copy would be created on the stack and then removed later. You could get a stack overflow though, if the array is large enough.

However you’d still have to copy that block of memory from the heap to the stack first I think, so accessing the array “in place” is often better and faster.

Ok I get it, I think I misunderstood your post.
The local variable array is created by C++'s mechanism, not allocated by Unreal, of course.
