The following doesn't look correct to me: If pool.allocate() is not supposed to throw an exception, you're constructing a node on a null pointer.

It's okay if chunk is zero. Placement new is declared with throw(), so according to (5.3.4/13) it indicates failure by returning a null pointer, and the constructor will not be called. In Christ, Steven Watanabe
