[ruby-core:59589] [ruby-trunk - Bug #9315] Segfault when calling super in rspec mocks with and_call_original [linux]

Issue #9315 has been updated by jgraichen (Jan Graichen).


=begin
I've finally had time to test my test suite on current ruby heads and encountered some other similar problems again.

Given the following example:

  module Persistence
    def save!
      # save to disk etc.
      puts "saved!"
    end
  end

  module Validation
    def valid?(context)
      true
    end

    # Hook save!
    def save!(*args)
      return false unless valid? :create
      super
    end
  end

  class Model
    include Persistence
    include Validation
  end

  Model.new.method(:save!).call

On (({ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux]})):

  > ruby test.rb
  saved!

On (({ruby 2.0.0p377 (2014-01-03 revision 44491) [x86_64-linux]})):

  > ruby test.rb

Bug #9315: Segfault when calling super in rspec mocks with and_call_original [linux]

Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN


I've tried running my test suite [1] on Ruby 2.1 resulting in segmentation faults. I've created a smaller rspec test [2] reproducing the segfault. I still haven't found a way to reproduce the segfault without rspec mocks. Run the example via `rspec test.rb`. Same script on Ruby 2.0 works. Used linux is a Debian Sid.

[2] https://gist.github.com/jgraichen/8159849

I've attached the segfault output.
