Rails core - Jul 2006 - [ActiveSupport] Binding.of_caller and ruby 1.8.5

Hi,

Does anyone tried ruby 1.8.5 ?

Binding.of_caller seems broken even for the basic example :

$ cat test_binding_of_caller.rb
require ''activesupport/lib/active_support/binding_of_caller''
def inc_counter(amount = 1)
  Binding.of_caller do |binding|
    inc = eval("lambda { |arg| counter += arg }", binding)
    inc.call(amount)
  end
end
counter = 0
2.times { inc_counter }
p counter # => 2

$ ruby test_binding_of_caller.rb
test_binding_of_caller.rb:7:in `inc_counter'': undefined method
`+'' for
nil:NilClass (NoMethodError)
        from test_binding_of_caller.rb:5:in `inc_counter''
        from
./vendor/activesupport/lib/active_support/binding_of_caller.rb:80:in
`of_caller''
        from test_binding_of_caller.rb:3:in `inc_counter''
        from test_binding_of_caller.rb:9
        from test_binding_of_caller.rb:9

Any idea about that ?

Cheers,
