Issue #9721 has been reported by Wei Hu.

----------------------------------------
Bug #9721: super: no superclass method in Ruby 2.1.1
https://bugs.ruby-lang.org/issues/9721

* Author: Wei Hu
* Status: Open
* Priority: Normal
* Assignee: 
* Category: 
* Target version: 
* ruby -v: ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
Below code will result into error:
super: no superclass method `foo'for #<Object:0x002b0430670fe8> 

However, it can pass with Ruby 1.9 and I am not sure if it's feature changes or bug.

module A
  def foo
    puts "A"
  end
end
 
module B
  def foo
    puts "B"
    super
  end
 ub_meth = instance_method :foo
  define_method :foo do
    ub_meth.bind(self).call()
 end
end
a = Object.new
a.extend A
a.extend B
a.foo
