DL::Function#bound? and unbind raise error when Fiddle is available
Description
When Fiddle is available, DL::Function#unbind raises error.
require 'dl'
require 'dl/func'
include DL
f = Function.new(CFunc.new(0, TYPE_INT, 'test'), [TYPE_INT, 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 method ptr' 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, TYPE_INT, 'test'), [TYPE_INT, 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 method ptr' for #<#Class:0x007f6708842d78:0x007f6708842cb0> (NoMethodError)
