This is not a Ruby but a shell issue. Use

  system "ruby", "popi.rb", $ie

Further, command arguments may only be strings. If you
really need to do this anyway you could marshal the object:

----sub.rb
class C ; end
c = Marshal.load ARGV.shift
puts c.inspect
----------

----main.rb
class C ; end
c = C.new
system "ruby", "sub.rb", Marshal.dump(c)
-----------

I doubt whether objects that are connected to processes
outside could be marshalled at all.
