Hi, 

The Seg fault happens when invoking the test below (Ruby 1.9.3p194 on Windows XP SP3). Ran Ok when commented out $semaphore.lock line.
 
  $semaphore = Mutex.new

  # ..
  def test_run_spec_file_web
    $LOADWISE_PREVIEW = true
    tmp_spec_file = SpecFile.new
    tmp_spec_file.file_path = test_project_file("sign_in_test.rb")
    thread = RSpec2Executor.run_spec(tmp_spec_file)
    thread.join
  end

in RSpec2Executor class
  
  ## Invoke a RSpec to run Watir (OLE) test
  # 
  def self.run_spec(spec)
    thread = Thread.new do
       $semaphore.lock  # if commented out this line, it is fine
       test_file = spec.file_path
       RSpec::Core::Runner.run([test_file])
    end
  end
