      Here's a script demonstrating the bug:

      require 'bundler/inline'

gemfile do
  source "https://rubygems.org"
  gem "mongoid"
  gem "ostruct" # get rid of warnings in newer Rubies
end

Mongoid.configure do |config|
  config.clients.default = {
    hosts: ['localhost:27017'],
    database: 'mongoid_test',
  }
end

class Article
  include Mongoid::Document

  embeds_many :authors
end

class Author
  include Mongoid::Document
  include Mongoid::Timestamps unless ENV["SKIP_TIMESTAMP"]

  field :name, type: String
  embedded_in :article

  before_save :destroy_if_rodrigo

  def destroy_if_rodrigo
    destroy if name == "Rodrigo"
  end
end

article = Article.create
article.authors << Author.new(name: "Rodrigo")
article.save

      Run it without including Mongoid::Timestamps:

      > SKIP_TIMESTAMP=1 ruby mongoid-frozen-attributes-bug.rb

      Now try with Mongoid::Timestamps:

      > ruby mongoid-frozen-attributes-bug.rb

      By the way, `ostruct` should be added as a dependency.
