disturbing issue I'm having with LinkedList in C language, when I count how many nodes should be

LL count: 1

void addLL(LL * head)
{
LL *newNode;
LL *tail = getLastNode(head);

newNode = malloc(sizeof(LL));
if(newNode != DEF_NULL)
{
    newNode->ID=-1;
    newNode->TCB=-1;
    newNode->next = DEF_NULL;

    if(!head) head = newNode;
    else tail->next = newNode;      
}   
}

LL * getLastNode(LL * head)
{
    LL *temp = head;
    while(temp->next != DEF_NULL)
    {
        temp = temp->next;
    }
    return temp;
}

CPU_INT32U countLL(LL * head)
CPU_INT32U countLL(LL * head)
{
    CPU_INT32U elements = 0;
    LL * temp = head;
    while(temp->next != DEF_NULL)
    {
        temp = temp->next;
        elements++;
    }
    return elements;
}

LL* list;

addLL(list);
int count = countLL(list);
Debug_LOG("LL count: %i", count);
