Bug #2001: StringScanner#string= dups and freezes when it shouldn't
http://redmine.ruby-lang.org/issues/show/2001

Author: Aaron Patterson
Status: Open, Priority: Normal
Category: ext
ruby -v: ruby 1.9.2dev (2009-08-27 trunk 24678) [i386-darwin9.8.0]

StringScanner#string= will dup the target string and then freeze the duplicate string.  It should not do this.

I've attached a patch which demonstrates the problem and fixes it.
