Segfault when upgrading to ruby 2.1


I am trying to upgrade our Sinatra app to version 2.1 and getting a
segfault when trying to run the tests. Can someone help me with finding
out where the problem is? Is it a gem or is it ruby?

Attached are the

  • segfault.txt the segfault message
  • Gemfile.lock.txt my Gemfile.lock with all dependencies

I am on a mac, mavericks, and using the latest rbenv.

Thanks in advance.
