Bug #8965: SEGV when a refined method is undefined by undef

• Status: Closed
• Assignee: shugo (Shugo Maeda)
• Target version: 2.1.0
• ruby -v: ruby 2.1.0dev (2013-09-27 trunk 43073) [i686-linux]
• Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN

[shugo (Shugo Maeda)]

The following code causes SEGV:

module Foo
refine Object do
def foo
puts "foo"
end
end
end

using Foo

class Object
undef foo
end

foo

I guess undef is not aware of refinements.

I reported this issue to ruby-dev by accident, so refiled as #8966.
