First I found a bug when Pathname#expand_path with 'c:' on Windows.

C:>ruby -rpathname -e "p Pathname.new('c:').expand_path"
c:/usr/lib/ruby/1.9.1/pathname.rb:596: [BUG] Segmentation fault

And I noticed that the real cause of error is in File.expand_path('c:')

C:>ruby -e "p File.expand_path('c:')"

In Ruby 1.9.1, this works fine.

C:>ruby -ve "p File.expand_path('c:')"
