Subject: [ruby-core:67081] [ruby-trunk - Bug #10638] [Open] Keyword Hash processing is inconsistent

Issue #10638 has been reported by Brian Shirai.

----------------------------------------
Bug #10638: Keyword Hash processing is inconsistent
https://bugs.ruby-lang.org/issues/10638

* Author: Brian Shirai
* Status: Open
* Priority: Normal
* Assignee: 
* Category: 
* Target version: 
* ruby -v: ruby 2.2.0dev (2014-06-05 trunk 46353) [x86_64-darwin13]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
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.
