gcc atomic built-in functions: any known conflicts within multithreading environments?

So, I want to avoid future problems when using __sync_fetch_and_add in a context of Boost-based multithreaded application.

Any chance that a low-level threading implementation used by Boost (pthreads here) would affect the functionality of buitins?

The builtins are the intrinsics.

They don't make assumptions about the libraries that will be used in applications.

There is no way it can interfere.

(On a tangent: Some libraries, like Boost Asio, optionally can use C++11 atomics instead of boost::detail::atomic_count (doc))
