byebug: Byebug doesn't play nice with bootsnap

Problem description

Byebug works fine the first time I add a debugger statement, but then when any other code is changed, the next time the breakpoint is hit, it seems to stop in some internal rails/other gem code. The issue is only alleviated by restarting the server, which can become time consuming when trying to debug an issue.

Expected behavior

The breakpoint should be retained even after code is changed.

Actual behavior

The breakpoint works fine the first time, but as soon as code is changed and the breakpoint is hit again, it seems to stop in internal rails code.

Steps to reproduce the problem

Simple example in HomeController:

class HomeController < ApplicationController
  before_action :redirect_signed_in_user, only: :welcome

  def welcome; end

  def redirect_signed_in_user
    debugger
    redirect_to root_url if user_signed_in?
  end
end

Works as expected

[20, 29] in /Users/ashwinhegde/code/apps/o3_crm/app/controllers/home_controller.rb
   20:
   21:   private
   22:
   23:   def redirect_signed_in_user
   24:     debugger
=> 25:     redirect_to root_url if user_signed_in?
   26:   end
   27:

Change some code, any code. Next time the breakpoint is hit - some internal devise code:

[117, 126] in /Users/ashwinhegde/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/devise-4.4.3/lib/devise/controllers/helpers.rb
   117:             opts[:scope] = :#{mapping}
   118:             warden.authenticate!(opts) if !devise_controller? || opts.delete(:force)
   119:           end
   120:
   121:           def #{mapping}_signed_in?
=> 122:             !!current_#{mapping}
   123:           end
   124:
   125:           def current_#{mapping}
   126:             @current_#{mapping} ||= warden.authenticate(scope: :#{mapping})
(byebug)
