            Bug ID: 31092
           Summary: clang-format Emacs integration breaks on Windows
           Product: clang
           Version: 3.9
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

Running `clang-format-buffer` from clang-format.el on any file that contains
multiple lines under Windows throws an error, even if the file contains only
ASCII characters:

    (clang-format failed with code 1: error: invalid length 34, offset + length
(34) is outside the file.)

The issues comes from the fact that Emacs uses `undecided-unix` encoding by
default to send data to subprocesses, but `undecided-dos` to receive data from
them, as shown by calling `describe-coding-system` on any buffer.

This problem can be fixed by calling `(setq default-process-coding-system
'(undecided-dos . undecided-dos))` in `.emacs`.

I am not sure if this issue can or should be solved at clang-format.el level,
but I thought it is worth pointing out since it affects every Emacs user on
Windows that hasn't fiddled with the `default-process-coding-system` variable.
