You have left out the quotes in << puts #{name} >>. This results in
(for example):

def hi
  puts hi
end

...which results in the function calling itself forever. On my machine
(exact same Ruby version and patchlevel, but on Windows) I get a
SystemStackError:

(eval):2:in `hi': stack level too deep (SystemStackError)
        from (eval):2:in `hi'

But it's understandable that you core dump instead.

Hope this helps.
