Bug #10659: can't dup Fixnum (TypeError)

[janko (Janko Marohnić)]

In Ruby 2.2 (older versions are good) there is a bug with unnamed keyword arguments when super is used.

module Foo
  def foo(**)
  end
end

class Bar
  include Foo

  def foo(bar: "bar", **)
    super
  end
end

Bar.new.foo # `dup': can't dup Fixnum (TypeError)

It happens when super is called. If I give the keyword arguments a name (** => **options) or if I remove the default keyword argument (bar: "bar"), the error doesn't happen.

parse.y: fix internal IDs conflict

• parse.y (f_kwrest, new_args_tail_gen): unnamed rest keyword and
  keywords bits arguments should be unique. since internal IDs
  depend on the local variable index in the current scope, new ID
  should be made before popping those vtables.
