I had installed debugger gem on Rails 4 application, and had put "debugger" inside controller's private method(before_action method). Below is the code snippet from users_controller.rb.

Rails 4.0.0

class UsersController < ApplicationController
  before_action :is_signed_in, only: [:new, :create]
  
    def new
    @user = User.new
  end

  def create
    @user = User.new(user_params)
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to the Sample App!"
      redirect_to @user
    else
      render 'new'
    end
  end

  private
     def is_signed_in
      debugger
      redirect_to(root_url) if signed_in?
    end
end

Though I'm not able to reproduce it, still thought of sharing it here. I could find two crash reports in my Library.. Attaching both of them.

Here is the trace:

ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin11.4.2]
