Bug #10638: Keyword Hash processing is inconsistent

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.2.0dev (2014-06-05 trunk 46353) [x86_64-darwin13]
• Backport: 2.0.0: REQUIRED, 2.1: REQUIRED

[brixen (Brian Shirai)]

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.

Works ok on current trunk (48948).

[brixen (Brian Shirai)]

Sorry, I had an old MRI version selected in chruby, this appears to work correctly on trunk.
