ruby-core #77952
Issue #11186 has been updated by Shugo Maeda.
Backport changed from 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN to 2.1: DONTNEED, 2.2: DONTNEED, 2.3: DONTNEED
The bug was fixed in Ruby 2.3, and need not to be backported to prior versions, I think.

* Author: Shugo Maeda
* Status: Closed
* Priority: Normal
* Assignee: Shugo Maeda

----------------------------------------
In the following program, D.new.bar returns :original, but should return :refined.
```
class C
def foo
:original
end
end
class D < C
alias bar foo
end
module M
refine D do
def bar
:refined
end
end
end
using M
p D.new.bar
```
This bug seemed to be introduced in r45367.
