It seems like they've made the classic mistake with C++ parsers of reinventing the wheel. I have never used an IDE which is capable of correctly parsing all the C++ code I've used. The notable exception is anything based on clang, which is usually flawless (as you would expect). If CLion had been based on clang then they would have saved themselves a lot of work and ended up with a better performing product. Presumably the reason they didn't had something to do with licensing.
