从链表中正确删除元素?指针出现内存错误

我正在实现一个具有remove_entry函数和clear_table函数的哈希表.现在，我收到与remove_entry函数有关的内存读取错误.并非常感谢您的帮助

I'm implementing a hashtable that has a remove_entry function as well as a clear_table function. Right now I'm getting memory read errors pertaining to the remove_entry function. And help would be greatly appreciated

这些是我的结构:

typedef struct bucket {
   char *key;
   void *value;
   struct bucket *next;
} Bucket;

typedef struct {
   int key_count;
   int table_size;
   void (*free_value)(void *);
   Bucket **buckets;
} Table;

这是我的职能:

int remove_entry(Table * table, const char *key){
    unsigned int hc = 0;
    Bucket *curr_b;
    Bucket *next_b;

    if(table == NULL || key == NULL){
        return FAIL;
    } else {
        hc = hash_code(key)%(table->table_size);
        if(table->buckets[hc] != NULL){
            curr_b = table->buckets[hc];

            /*Check the buckets in linked list*/
            while(curr_b != NULL){
                next_b = curr_b->next;

                if(strcmp(curr_b->key,key) == 0){
                    free(curr_b->key);
                    if(table->free_value != NULL){
                        table->free_value(curr_b->value);
                    }
                    free(curr_b);
                    curr_b = NULL;
                    table->key_count--;
                    return SUCC;
                } else {
                    curr_b = next_b;
                }
            }
            return FAIL;
        }
        return FAIL;
    }
}

在删除条目并尝试读取表之后，发生了内存泄漏.我认为我删除的内容不正确.

The memory leaks come after removing an entry, and trying to read the table after. I don't think I removed things right.

内存错误:

无法弄清楚如何从终端复制/粘贴，所以他们都说

Can't figure out how to copy/paste from terminal, so they all say things like
