Vim crashes with version c963df1

[felixendres]

Lately my clang_complete setup appears to be much less stable. Often the clang library crashes, but sometimes it even kills vim. I installed it via vim-plug, which downloaded version c963df1. Is clang_complete working with libclang 4.0?

Below is the error message with (manual translations of some German). And below that my vimrc settings.

Vim: Caught deadly signal SEGV Vim: preserving files...

let g:clang_auto_user_options = "compile_commands.json"

I'd appreciate any help, as code completion is quite important for me.

I think it's the same as #446, where wilywampa speculated that it's due to Vim's python interface. 4.0.0 might have also broken come of the C API, but I don't know if it's the case.

I totally forgot, that I reported this problem already in January in the issue you mentioned. Anyway, I have the feeling that it got worse in the last month or so.
