Problem subclassing IO and writing on Windows

[Berger, Daniel]

Hi all,

Windows XP Pro
Ruby 1.8.2

The following snippet dies on Windows with:

subtest.rb:8:in `write': not opened for writing (IOError)
from subtest.rb:8:in `write_stuff'
from subtest.rb:14

Works fine on *nix. Am I doing something wrong? Or is this a bug?

# subtest.rb
class MyIO < IO
def initialize(arg) =20
super(arg)
binmode =20
end
=20
def write_stuff
write("Hello World")
end
end

mio =3D MyIO.new(File.open("test.txt","wb+").fileno)
mio.write_stuff
mio.close
puts "Done"

Regards,

Dan
