        <pre>clang version 5.0.1
Arch linux

Snippet of init.vim file:

function FormatCPPFile()
  let l:lines = "all"
  pyf /usr/share/clang/clang-format.py
endfunction

autocmd FileType cpp map <buffer> <silent><C-I> :call FormatCPPFile()<CR>

Here's what I get in nvim (NVIM v0.2.2) when C-I was pressed:

error: invalid <start line>:<end line> pair                                     
No output from clang-format (crashed?).
Please report to bugs.llvm.org.

Looks like the problem is here:
nvim -d cfe-5.0.0.src/tools/clang-format/clang-format.py
cfe-5.0.1.src/tools/clang-format/clang-format.py

Here is the difference:
(cfe-5.0.0) line 65:  lines = vim.eval('l:lines')
(cfe-5.0.1) line 65:  lines = ['-lines', vim.eval('l:lines')]</pre>
        </div>
