Rails - Aug 2011 - belongs_to + :inverse_of + accepts_nested_attributes_for causes stack overflow on save

Hello, i have just submitted a bug report, but maybe anybody has some
experience with this problem?

Here are the steps to reproduce the error:

Create an application with 2 models:

$ rails new assoc_test_app
$ cd assoc_test_app
$ rails generate model Person name:string
$ rails generate model Member person_id:integer
$ rake db:migrate

Set up an association:

  class Member < ActiveRecord::Base
    belongs_to :person, :inverse_of => :member
    accepts_nested_attributes_for :person
  end

  class Person < ActiveRecord::Base
    has_one :member
  end

Now, in concole (rails c) do:

  m = Member.new
  m.build_person(:name => ''John2'')
  m.person.save

This produces "SystemStackError: stack level too deep".

Without :inverse_of it works fine.

Is there a reason not to use :inverse_of with
accepts_nested_attributes_for, or is it just a bug?

Thanks.

Alexey.
