Crash "missing brace not found"

[lee-dohm]

Minimal Repro

require 'logger'

logger = Logger.new(STDOUT)
logger.debug { "foo #{logger}" }

Fails on line 4 column 13 with the message "missing brace not found". Curiously, column 13 is the space character before the first brace on that line, not the brace itself. Could there also be an off-by-one error in calculating the column for exceptions?

I think you're running an older version of rubocop (with ruby 2.0) and have encountered a bug previously reported in issue #41 and corrected in rubocop-0.4.1. Also column numbers start at 0, unlike line numbers, which start at 1. So there's a left brace at column 13.

You are correct. Updating to the latest version of rubocop fixed the crash. Thanks!
