Description

When Fiddle is available, DL::Function#unbind raises error.

require 'dl'
require 'dl/func'
include DL
f = Function.new(CFunc.new(0, TYPEINT, 'test'), [TYPEINT, TYPE_INT])
f.bind { |x,y| x + y }
f.unbind

The above code raises the following error in "f.unbind".
/XXXX/lib/ruby/2.0.0/dl/func.rb:160:in unbind': undefined methodptr' for #<#Class:0x007f8e8f29ae08:0x007f8e8f29ad40> (NoMethodError)
from -:6:in `'

When Fiddle is available, DL::Function#bound? also raises error.

require 'dl'
require 'dl/func'
include DL
f = Function.new(CFunc.new(0, TYPEINT, 'test'), [TYPEINT, TYPE_INT])
f.bind { |x,y| x + y }
f.bound?

The above code raises the following error in "f.bound?".
/XXXX/lib/ruby/2.0.0/dl/func.rb:174:in bound?': undefined methodptr' for #<#Class:0x007f6708842d78:0x007f6708842cb0> (NoMethodError)
