https://bugs.ruby-lang.org/issues/9461#change-44691

* Author: Agis Anastasopoulos
* Status: Open
* Priority: Normal
* Assignee: Koichi Sasada
* Category: core
* Target version: current: 2.2.0

The following causes a segfault in 2.1.0, but works fine in 2.0 and 1.9:

    module A
      def require(_)
        super
      end
    end

    class Object
      include A
    end

    ['foo'].map(&method(:require))
