— test.rb —  
require ‘pathname’  
puts Pathname.new(’.’).realpath  
— test.rb —

always produces:

c:/ruby/lib/ruby/1.8/pathname.rb:341:in `lstat': Invalid argument - /c: (Errno::EINVAL) from c:/ruby/lib/ruby/1.8/pathname.rb:341:in`realpath’  
from test.rb:2

any ideas? seems like Pathname doesn’t support windows at all?

where to submit this kind of bugs?
