[indyarocks (Chandan Kumar)]

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:
