I presume you're talking about the i386 here... There are problems with gcc's constraint checking - last time I tried, I couldn't write a set of operand constraints (for these atomic operations) that would compile both with and without "-O". You could try using the "gcc <= 2.8 version" of the ATOMIC_ASM macro - based on a quick check, this appears to work correctly with "-O0".
