Bug that should cause SystemStackError segfaults under Ruby 2.1

Added by Perceptes (Jimmy Cuadra) about 10 years ago. Updated over 4 years ago.

ruby -v:
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]
Backport:
[ruby-core:60601]

Description

Using rspec-core.3.0.0.beta1 and ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]:

require "rspec"
require "rspec/autorun"

describe "Ruby 2.1 segfault" do
  let(:argument) { double }

  subject { subject.new(double) }

  it "will segfault" do
    subject
  end
end

Running this program under Ruby 2.0 results in a SystemStackError. Under Ruby 2.1, Ruby segfaults.

Please try your code with Ruby 2.1.1

I can reproduce almost exactly this issue on 2.1.1p97 p76. Full details and steps I used to reproduce are in https://github.com/danielfone/rspec-memoization-segfault

Updated by jafergus (James Ferguson) almost 10 years ago

I've reproduced the same thing with two doubles that reference each other. Also on 2.1.1-p76.

For what it's worth, this appears to be fixed in ruby-2.2.0-preview2.
