The real name of this function is __sync_add_and_fetch().

See: http://gcc.gnu.org/onlinedocs/gcc-4.3.2/gcc/Atomic-Builtins.html

If you are compiling all the code in your program, including the 'one of

You need to post a small, complete, and runnable testcase for us to be 
able to help much more.
