Description

=begin
The following code behaves differently under Ruby 1 and Ruby 2.

module Fun
def hello
orig_hello
end
end

module M1
def hello
p 'hello!'
end
end

module M2
def hello
super
end
end

class Foo
include M1
include M2

alias_method :orig_hello, :hello
include Fun

end

Foo.new.hello

% ruby -v fun.rb
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-darwin12.5.0]
"hello!"

% ruby -v fun.rb
ruby 2.1.0dev (2013-12-10 trunk 44126) [x86_64-darwin12.0]
fun.rb:3: stack level too deep (SystemStackError)

Let's see if this is an intended spec change or a bug.
