Segment fault when trying to stop profiler by visiting /__stop__ on Rails 4.0.5 / Ruby 2.1.1 about rack-perftools_profiler HOT 1 OPEN

Thanks for the report. perftools.rb does not work with Ruby 2.1. I may add
support for Stackprof (https://github.com/tmm1/stackprof) but I haven't yet
had time yet.

Do some requests.
Then visit http://localhost:3000/**stop**

The server (started with rails s) crashes.
