The following:

Fiber.new { puts "foo" }.resume

produces a segfault with the following output.

Sorry, I reported this in the wrong project earlier. I'm not seeing the same issue on 1.9.3.

Hi, Dan

Thank you for your reporting.
I think 'Backport92' is right project to submit backport request.
I close this ticket as duplicated with #4945.
