Comment(by watson1978@…):

 IO#sysopen creates the IO's object, and returns file descriptor from its
 object. [[BR]]
 When invoked GC finalizer for its object, it seems to occurs Errno::EBADF.

  1. IO#sysopen creates IO's object, returns file descriptor.
  2. IO.new creates IO's object from file descriptor.
  3. GC finalizer run for object of IO#sysopen
     - invoke rb_objc_io_finalize
     - -> close file descriptor by rb_io_close
     - -> same descriptor number is used by IO.new's object.
  4. IO#read -> Errno::EBADF


 I think that should not create an IO's object in IO#sysopen.
