Subject: [ruby-core:38356] [Ruby 1.9 - Bug #5070][Assigned] CSV.generate should not modify the given option hash


Issue #5070 has been reported by Marc-Andre Lafortune.

----------------------------------------
Bug #5070: CSV.generate should not modify the given option hash
http://redmine.ruby-lang.org/issues/5070

Author: Marc-Andre Lafortune
Status: Assigned
Priority: Normal
Assignee: James Gray
Category: lib
Target version: 1.9.3
ruby -v: r32598


Currently:

    CSV.generate( {}.freeze ) # => RuntimeError: can't modify frozen Hash

I'm not sure where these tests would ideally go; In the attached patch, I've put them at the end of csv/test_interface

If you can, please make the modifications you see fit, or else I'll commit this in a of week or two.
