----------------------------------------
The following spec causes a segfault for me in ruby 2.1.1 on OS X 10.9.2:

~~~
class A
  def a
    'a'
  end
end

class B
  def b
    'b'
  end
end

describe 'segfault' do
  it 'should make unused recorders' do
    expect_any_instance_of(A).to receive(:a)
    expect_any_instance_of(B).to receive(:b)
  end
  
  it 'should crash ruby' do
    A.new.a
    B.new.b
  end
end
~~~

Some more info:

~~~
$ ruby -v
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]
$ bundle exec gem list

I've also attached the crash report generated by OS X.  Let me know if you need some more info.  Sorry if this is a duplicate, I found some similar looking reports (#9309, #9461, #9315), but I don't really know enough to recognize if they are exactly the same issue.
