    pleae help. Why I get "Run time error" for the following code

    Node *deleteDuplicates(Node *head){

    assert(head);
    Node *next_next;
    Node *cur = head;
    while (cur->next){
        while(cur->val==cur->next->val){
            if (!cur->next->next)   {delete cur->next; cur->next=NULL; return head;}
            next_next=cur->next->next;
            delete cur->next;
            cur->next=next_next;
        }
        cur=cur->next;
    }
    return head;
    

    }
