title: therubyracer v8 init.so Segmentation fault
body: <p>I'm running Centos 6.5, apache2 and ruby 2.1.2p95 and trying to start Puma server for my sinatra app. It continues to fail giving an extremely long output but it appears the real error is:</p>
  
  <pre><code>/usr/lib/ruby/gems/2.1.0/extensions/x86_64-linux/2.1.0-static/therubyracer-0.11.3/v8/init.so: [BUG] Segmentation fault at 0x0000000007fc90
  </code></pre>
  
  <p>here's a bigger chunk of the output:</p>
  
  <pre><code>-bash-4.1$ bundle exec puma -e staging

  <p>I was using a newer version of therubyracer, but saw a post where someone suggested rolling back and that didn't work.</p>
  
  <p>It also seems like this isn't always the error I'm getting. one time it was the sass gem that failed, but this was the most often</p>
