title: How can I profile Ruby code in 1.9.2?
body: <p>What can I use to profile code in 1.9.2?  All of the versions of ruby-prof I've found segfault against 1.9.2.</p>
  
  <p>For instance, when I add</p>
  
  <pre><code>gem "ruby-prof"
  </code></pre>
  
  <p>to my Rails project's Gemfile and run</p>
  
  <pre><code>bundle
  bundle exec ruby-prof config/environment.rb
  </code></pre>
  
  <p>I get a segfault.</p>
  
  <p>Is there a new profiling gem in town?  Is there a way to make ruby-prof play nice?</p>
