Может кто-нибудь увидеть, где я продолжаю получать эту ошибку "переменная может быть унифицированным"

Question

Я продолжаю получать ошибки компиляции из этого куска кода.

Я пытался использовать mallocing, но это не помогло.

else{

    thread_queue* new_running_queue = ready_queue -> link; //copy head
    ready_queue = ready_queue->link; //set head to next in ready_queue


    thread_queue* end = append_thread();//add thread to end of linked list
    end->thread = current_running_thread;
    int err = getcontext(current_running_thread->thread_context);//copy current state

    assert(!err);
    //copy manually of context in the last node in link list

    set_ucontext(end,current_running_thread->thread_context);

    //set the current running thread to the thread at the beginning of queue

    current_running_thread = new_running_queue->thread;
    current_running_thread->thread_id= new_running_queue->thread->thread_id;
    free(new_running_queue);

}
