Odd Indent Error With Coffee Script 1.6.3

I updated to the latest coffee script and still am getting the following error: Any ideas on what might be causing the error? 

ie = (->
  undef = undefined
  v = 3
  div = document.createElement("div")
  all = div.getElementsByTagName("i")
    while div.innerHTML = "<!--[if gt IE " + (++v) +"]><i></i><![endif]-->"
  all[0]

  (if v > 4 then v else undef)
())

I've removed this line from a massive js file I'm converting to coffee script and it all compiles fine. Can anyone see what might be wrong with this?

SyntaxError: unexpected INDENT
>> On line: 816
>>     while div.innerHTML = "<!--[if gt IE " + (++v) +"]><i></i><![endif]-->"
>> ^

Assuming you got your JS to do this from here, then you have translated the JavaScript to CoffeeScript poorly.

What you want is something like this:

ie = do ->
  version = 3
  div = document.createElement 'div'
  all = div.getElementsByTagName 'i'

  testVersion = ->
    div.innerHTML = "<!--[if gt IE #{version}]><i></i><![endif]-->"
    all[0]

  while testVersion()
    version += 1

  if version > 4 then version else no
