C++ is still plenty viable, but if you like avoiding bugs, John Carmack seems to have come to the conclusion that using a functional style (which is not exactly encouraged by C++) is advantageous: http://gamasutra.com/view/news/169296/Indepth_Functional_pro...
"My pragmatic summary: A large fraction of the flaws in software development are due to programmers not fully understanding all the possible states their code may execute in. In a multithreaded environment, the lack of understanding and the resulting problems are greatly amplified, almost to the point of panic if you are paying attention. Programming in a functional style makes the state presented to your code explicit, which makes it much easier to reason about, and, in a completely pure system, makes thread race conditions impossible.
"No matter what language you work in, programming in a functional style provides benefits. You should do it whenever it is convenient, and you should think hard about the decision when it isn't convenient."
