Issue #6239 has been reported by mudge (Paul Mucur).

Bug #6239: super Does Not Pass Modified Rest Args When Originally Empty
https://bugs.ruby-lang.org/issues/6239

Author: mudge (Paul Mucur)
Status: Open

Target version: 
ruby -v: 1.8.7-p358


Given the following code:

    class A
      def a(*args)
        args
      end
    end

    class B < A
      def a(*args)
        args << "foo"

        super
      end
    end

1.8.7-p358> B.new.a("bar")
=> ["bar", "foo"]
1.8.7-p358> B.new.a
=> []

But:

1.9.2-p290> B.new.a("bar")
=> ["bar", "foo"]
1.9.2-p290> B.new.a
=> ["foo"]

The 1.9.2 behaviour is more predictable than 1.8.7, should this be backported or is this expected behaviour?
