If I run the below command on Windows (Ruby 1.9.3-p362) -

status = POpen4::popen4("dir") do |stdout, stderr, stdin, pid|
  puts "pid        : #{ pid }"
  puts "stdout   : #{ stdout.read.strip }"
  puts "stderr    : #{ stderr.read.strip }"
end

I get the below error -

ruby build\SubProcess.rb
pid : 6884
stdout : Volume in drive C has no label.
Volume Serial Number is FEB9-0047
