Bug #2046: (IO|File)#binmode is Inconsistent Across Versions
http://redmine.ruby-lang.org/issues/show/2046

Author: Run Paint Run Run
Status: Open, Priority: Normal
Category: core
ruby -v: ruby 1.9.2dev (2009-09-03 trunk 24741) [i686-linux]

Presumably 1.8 or 1.9 are at fault.
  
  $ cat /tmp/bin.rb 
  f = File.new('/etc/passwd')
  f.close
  f.binmode

  $ ruby8 -v /tmp/bin.rb
  ruby 1.8.8dev (2009-07-01) [i686-linux]

  $ ruby -v /tmp/bin.rb
  ruby 1.9.2dev (2009-09-03 trunk 24741) [i686-linux]
  /tmp/bin.rb:3:in `binmode': closed stream (IOError)
	from /tmp/bin.rb:3:in `<main>'
