Nested use with factory girl causes `Segmentation fault`

[oleander]

I've this structure.

class StaticPlaylist < ActiveRecord::Base
  acts_as_superclass
end

class ImportedPlaylist < ActiveRecord::Base
  acts_as :static_playlist
  acts_as_superclass
end

class DigiPlaylist < ActiveRecord::Base
  acts_as :imported_playlist
end

When I try creating a DigiPlaylist using factory girl I get this error.

Here is the full stacktrace. It looks like an infinitive loop.

My factory looks like this.

FactoryGirl.define do
  factory(:digi_playlist) do
  end
end

I looks like the problem is explained in pull request #8.

endless loop at time of creation in some cases (as example creation through Factory Girl Proxy)

How can we solve this?
