Looks like MRI 1.9 has the same problem:
irb(main):001:0> /\n(\.\/)?(.*\.rb):[\d]+:\Z?/ SyntaxError: (irb):1: target of repeat operator is invalid: /\n(\.\/)?(.*\.rb):[\d]+:\Z?/ from bin/irb:12:in `<main>' irb(main):002:0> -

FWIW, JRuby also has the same issue using JOni, the Java Oniguruma port. So it's something inherent in anything Oni-based.
