PIC24FJ256GB106链接列表失败

您好，我试着编辑一个反网络堆栈的一部分，不使用Maloc，因为它总是失败。代码使用MALOC创建对象并插入到链表中。在下面的代码片段中，我已经注释出了MALOC。我的计划是创建结构体的本地实例并将其插入到列表中。我可以把2个项目插入到我的列表中，当试图添加第三时，列表没有被正确地终止，我输入了无限的while循环。有人知道为什么我的名单没有被正确地终止吗？此代码简单地将元素添加到列表中，整个代码随后将一些变量设置为默认值。

    Hello,

I am trying to edit part of a backnet stack to not use malloc as it always fails. The code uses malloc to create an object and insert into a linked list. In the following code snippet I have commented out the malloc. My plan is to create a local instance of the struct and insert that into my list. I am able to insert 2 items into my list, when trying to add the third, the list is not properly terminated and I enter an infinite while loop. Can anyone see why my list is not properly terminated?

CHobjects* newNode(instance, channel, name, description)
{
CHobjects *node;
CHobjects newNode;

    node=CHobjects;
    while(node!=NULL)
    {
        if(node->instance==instance)
            return
        node=node->next;
    }
    if(strlen((char *)objectName)>objectNameMax || strlen((char *)description)>descriptionMax)
        goto cc8; //fail name or description is too long
// if((node=(CHobject *)malloc(sizeof(CHobject)))==NULL) //get a block of space for this object's info
// goto cc8; //fail if we can't get space for it
    test.next=CHobjects; //link on to list
    CHobjects=&test;
    CHcount++;
}

This code simply adds the elements to the list, the whole code would afterwards set some variables to default values.
