Please open a new issue so we can discuss further. The mixing between pos and readline is not clear time and your test isn't helping in that area. Thank you. ---------------------------------------- Backport #6179: File::pos broken in Windows 1.9.3p125 https://bugs.ruby-lang.org/issues/6179#change-26455 Author: jmthomas (Jason Thomas) Status: Closed Priority: Normal Assignee: h.shirosaki (Hiroshi Shirosaki) Category: Target version: Calling the pos method on a File in the Windows version of Ruby on 1.9.3p125 moves the file pointer.
