I'm using g_atomic_int_set, g_atomic_int_get, g_atomic_int_xor and g_atomic_int_and to implement thread synchronization.

We really should add it. Without running my application within valgrind I get the following out of GDB.

I don't know much about CPU instructions because I normally just do C and I expect that everything just works fine. By the way in what bugzilla should I file that bug. On valgrind.org or maybe on fedoraproject.org? I'm using fedora 20-beta. Here's the output of lscpu.
