Range violation error in the code

[Ishan Thilina]

I can compile the following code. But when I run the program it gives me a
"core.exception.RangeError at untitled(34): Range violation
" error.

The code is as follows.

"
import std.stdio;

int main(char[][] args)
{
	 struct Node{
		int _value;
		Node* _next,_prev,_up,_down;
	}

		Node*[]  pointers;
		int i=0;

		auto  n=new Node;
		pointers[i]=n;

	return 0;
}

"

Here's the error.

As it seems the problem is with the line "pointers[i]=n". What's wrong here? :s
