Subject: [ruby-core:43542] [ruby-trunk - Bug #6179] File::pos broken in Windows 1.9.3p125


Issue #6179 has been updated by h.shirosaki (Hiroshi Shirosaki).

File pos_fix.patch added

Thank you for your work.
I confirmed the bug. io_unread() with mode "r" had a bug. IO#pos calls io_unread().

Trunk also has same bug.
I've created a patch which replaces io_unread(). Heesob's test case was passed.
`make test` && `make test-all` look fine.

The patch is against trunk.
Could you review and try the patch?

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.
