Vim segmentation fault when open

[nyibbang]

Hi ! First of all I must say I was very happy to find out today about your plugin, and I thank you for your work. But sadly I have been struggling with an issue when trying to use it.

I installed the plugin using Vundle, went into my ~/.vim/bundle/color_coded and accordingly to the README did :

mkdir build; cd build; cmake ..; make && make install

All went fine, it downloaded clang, compiled the code and installed it as ~/.vim/bundle/color_coded/bin/color_coded.so. I can even cd in the directory containing that library, do lua -l color_coded and get the LUA prompt.
Despite everything going well, when I tried to launch vim, I got the error color_coded unavailable: you need to compile it (see README.md) for some reason. I then tried to use :PluginUpdate to see if it would change anything, but since then when I try to launch vim, I get a segfault :

Vim: Caught deadly signal SEGV
Vim: Finished.
[1]    22076 segmentation fault  vim

I tried to wipe out my build and bin directory in color_coded and compile it again, it compiled fine but vim still segfaults. When I comment the line Plugin 'jeaye/color_coded' in my vimrc, vim opens fine.

I'm running Debian 8, with g++ 4.9.2, lua 5.1.5, vim 7.4.576 compiled with lua support.
I had this issue on commit d21d70f.

EDIT:
I just saw this in the README https://github.com/jeaye/color_coded#color_coded-crashes-on-startup but vim --version | grep jit prints nothing for me, so it doesn't seem to be linked.

Will you please paste the full output of vim --version?

[nyibbang]

Sure, here you go

[jeaye]

Thanks. This is a unique case, I think. Are there any peculiarities with your setup? This issue might be caused by lua or vim being compiled with a different version of GCC than color_coded, for example. Is any of the software involved self-compiled, or all standard from Debian?

[nyibbang]

I installed vim from the vim-gtk package, and lua from the list of dependencies you give in the readme : sudo apt-get install build-essential liblua5.1-dev lua5.1 libncurses-dev libboost-dev libz-dev cmake xz-utils.
It's a fairly new install of debian (from 3 weeks ago), so I haven't had time to pollute it yet. Everything is from standard debian repositories.

It looks like your vim is linked with lua 5.2 but color_coded is linked against 5.1. You will have to uninstall liblua5.1-dev so it does not get selected in the build process of color_coded (See #53) and install liblua5.2-dev lua5.2. Then you have to build color_coded again. I am not sure if make clean is enough. You should also remove your build directory and do a completly new build of color_coded.

[nyibbang]

Indeed, color_coded found lua5.1 and linked with it:

ldd colod_coded.so
[...]
    liblua5.1.so.0 => /usr/lib/x86_64-linux-gnu/liblua5.1.so.0 (0x00007f9c43ac1000)
[...]

And vim was using lua 5.2:

ldd /usr/bin/vim
[...]
    liblua5.2.so.0 => /usr/lib/x86_64-linux-gnu/liblua5.2.so.0 (0x00007f4088763000)
[...]

I uninstalled liblua.5.1-dev (sudo apt-get remove liblua.5.1-0-dev), installed liblua.5.2-dev instead (sudo apt-get install liblua.5.2-dev), removed my bin and build directories in color_coded, rebuilt from scratch and it works fine.
Thank you !

@nyibbang This may have been fixed, such that you don't need to mess with your packages, after #53 was merged. If you can check again, let me know.
