Use validates_associated with :reverse_of cause infinite loop

I am not able to reproduce it with rails edge. This is what I did

    # nested attributes
    create_table :surveys, :force => true do |t|
      t.string :name
    end
    create_table :questions, :force => true do |t|
      t.text :name
      t.integer :survey_id
    end


class Survey < ActiveRecord::Base

  has_many :questions, :dependent => :destroy, :inverse_of => :survey

  accepts_nested_attributes_for :questions

  validates_presence_of :name

  def self.lab
  end

end




class Question < ActiveRecord::Base
  belongs_to :survey, :inverse_of => :question
  validates_presence_of :question
  validates_associated :question

  def self.lab
  end

end


ree-1.8.7-2010.01 > survey = Survey.new :questions_attributes => {}
 => #<Survey id: nil, name: nil> 
ree-1.8.7-2010.01 > survey.valid?
 => false
