You mean that doing "r" (read) implies "binary"? because when open with "rb" works as expected:

 V:\>irb
 irb(main):001:0> f = File.open "foo", "rb"
 => #<File:foo>
 irb(main):002:0> f.readline
 => "Line one\r\n"
 irb(main):003:0> f.pos
 => 10
 irb(main):004:0> f.readline
 => "Line two\r\n"

But it fails when mode is implicit (only "r")

Confirmed it is a bug, assigning it.

Thank you.

Target version: 1.9.3
ruby -v: 1.9.3p125


Calling the pos method on a File in the Windows version of Ruby on 1.9.3p125 moves the file pointer. Thus it can not be called without side effect.
