Please see contributing.md.

At a glance this is crashing in libclang so perhaps it should be reported upstream.

[hardboydu]

Use the default .ycm_extra_conf.py make clang segmentfailt

Refer to the following link does not appear segmentfailt

[micbou]

Read carefully the C-family Semantic Completion section in the documentation and in particular:

See YCM's own .ycm_extra_conf.py for details on how this works. You should be able to use it as a starting point. Don't just copy/paste that file somewhere and expect things to magically work; your project needs different flags.
