ruby-mode 1.1 indents the following code like this

if true
  val = string.split(/=/)
puts val
end

The puts line should be indented so that it matches the val line.

If you look at line 522 of ruby-mode.el (version 1.1, from elpa, I suspect other versions have the same code at possibly different line numbers) it says

((looking-at "/=")
 (goto-char pnt))

if you change that to

((and (looking-at "/=") (not (looking-at "/=/"))
 (goto-char pnt)))

the above example is indented correctly.
