Is this the correct way to do a CAS2? and will it get rid of the ABA problem in lockless queues/stacks?
bool CAS2(uint32* ptr, uint32 oldVal, uint32 newVal,uint32* oldPopCount, uint32 newPopCount) {
	if(*ptr == oldVal && *oldPopCount < newPopCount) {
		*ptr = newVal;
		return true;
	}
	return false;
}
