Subject: [ruby-core:62669] [ruby-trunk - Bug #9849] [Assigned] gsub(String, String) doesn't work properly

Issue #9849 has been reported by Shugo Maeda.

----------------------------------------
Bug #9849: gsub(String, String) doesn't work properly
https://bugs.ruby-lang.org/issues/9849

* Author: Shugo Maeda
* Status: Assigned
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* Category: core
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-05-19 trunk 46010) [i686-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
gsub(String, String) doesn't work properly as follows:

```
$ ruby -ve 'puts "���������\"foo\"\n\"bar\"".gsub("\"", "\"\"")' 
ruby 2.2.0dev (2014-05-19 trunk 46010) [i686-linux]
���������""foo"
"bar""
```

The expected behavior is:

```
$ ~/.rbenv/versions/2.1.1/bin/ruby -ve 'puts "���������\"foo\"\n\"bar\"".gsub("\"", "\"\"")' 
ruby 2.1.1p76 (2014-02-24 revision 45161) [i686-linux]
���������""foo""
""bar""
```

It seems that the bug was introduced by r45451, so I assign this issue to nobu.
