Ruby 1.9.3 [BUG] Segmentation with rspec

Recently I dealt with an issue with Agile Affiliate so I’m going to catalogue it here. Long story short – I was using the ‘binding_of_caller’ gem for rails. Well, one of my contractors was using it in dev and never took it out of the Gemfile. However, just this sitting in the Gemfile caused all kinds of segmentation faults when running rspec. I google’d around, reinstaled Ruby 1.9.3 with settings from a few Stack Overflow posts but still had no luck. The gem was the problem I eventually found by git bisecting the issue.

The segmentation faults looked like this:

AgileAffiliate/gems/actionpack-3.2.11/lib/action_dispatch/testing/assertions.rb:2: [BUG] Segmentation fault
ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin12.2.0]
