unbounded memory usage when repeatedly calling Node::operator[const Key&] const

[GoogleCodeExporter]

What steps will reproduce the problem?

There is unbounded memory usage when repeatedly calling Node::operator[]& const 
with a key that does not exist.
This does not reproduce when calling the non const version.

Sample program:

#include <string>
#include "yaml-cpp/yaml.h"

int main()
{
    const YAML::Node node;

    std::string key = "doesnotexist";
    for (;; )
    {
        node[key];
    }
}

What is the expected output? What do you see instead?
Expected: the memory usage of this program stays consistent.
Actual: the memory usage of this program increases until the program crashes 
due to an out of memory error.

What version of the product are you using? On what operating system?
yaml-cpp-0.5.1

Please provide any additional information below.

Interesting! I'll look into it.

Fixed, r730c40a3fca54f5a829d1dd20f000e284099e1d8.

It was simply creating a new Node every call to operator[] const.
