* ruby -v: ruby 2.2.0dev (2014-06-05 trunk 46353) [x86_64-darwin13]
* Backport: 2.0.0: REQUIRED, 2.1: REQUIRED
----------------------------------------
An empty Hash passed to a method taking a keyword rest argument is not dup'd. A modification to the keyword rest Hash in the method modifies the object passed to the method.

This behavior differs from passing a non-empty Hash.
