--- Comment #1 from Denis Shelomovskij <verylonglogin.reg at gmail.com> ---
`Select` constructor is typesafe variadic function so `projection` array may be
constructed on stack and thus contains garbage after function returns, casting
this garbage to `Node` fails somewhere in D runtime.

To fix the code replace
---
this.projection = projection;
---
with
---
this.projection = projection.dup; // `dup` is added
---


P.S.
One should be aware of typesafe variadic functions danger and carefully read
docs [1].
