I could not reproduce the bug. I have tried on two Mac's and POWER5 Linux. What Mac and CPU do you use ? Has the CPU 64-bit mode ?
My mac is a 12" powerbook G4 1,33Ghz, with 1,25GB mem, so no 64 bit mode..
Could you do following:
echo 'int main() {}' > q.c cc -o q q.c gdb q b main run disassemble ___compare_and_swap32

OK, then I will do atomic operation using MacOSX builtin OSAtomicCompareAndSwap32Barrier()
