Bug(?): YcmRestartServer constantly shutting down

[Feve2]

Hello there,
I know that there is already an issue regarding this. I tried to post on that issue, but however I cant post it there. I want to use YCM mostly for C and golang-dev .Here are are some information:
OS: Linux kali 4.0.0-kali1-amd64 #1 SMP Debian 4.0.4-1+kali2 (2015-06-03) x86_64 GNU/Linux
Vim-Version: 2:7.4.488-7
Python-Version: 2.7.9-1

I always get the message:

The ycmd server SHUT DOWN (restart with :YcmRestartServer). Stderr (last 30 lines)

Equally, if I change the ycm_python_path in the .vimrc (which python-version should I reference there? I have 2.7.x, python, and python 3.x)?

Steps to reproduce

1. Edit your .vimrc, add the line Plugin 'Valloric/YouCompleteMe and save it.
2. Go again into vim, type :PluginInstall.
3. Wait until Vundle says it's done / You get the message that you should compile it.
4. Download Clang for x86_64 Ubuntu 14.04
5. Extract the content (the folders) into ~/ycm_temp/llvm_root_dir/
6. cd to ~/ycm_build.
7. Execute cmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=~/ycm_temp/llvm_root_dir . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp.
   The output I got said that all went successful:

(8). Execute make ycm_support_libs.
The output I got is basically:

Scanning dependencies of target BoostParts

(9). Open a .c file. You should see the message *The ycmd server SHUT DOWN[...]

Debug-Log:

-- Server crashed, no debug info from server

-- Server process ID: 4787

I think this is related to #1686. Could you copy the library file libclang.so.3.7 from ~/ycm_temp/llvm_root_dir/lib to the ycmd root folder ~/.vim/bundle/YouCompleteMe/third_party/ycmd and try again?

A 1000 thanks. Now its working!
