/in/hash.c:21:55: error: 'memset' call operates on objects of type 'KeyValue *' (aka 'struct KeyValue *') while the size is based on a different type 'KeyValue **' (aka 'struct KeyValue **') [-Werror,-Wsizeof-pointer-memaccess]
        memset(hashtable->table, 0, sizeof(hashtable->table));

/in/hash.c:21:55: note: did you mean to dereference the argument to 'sizeof' (and multiply it by the number of elements)?
        memset(hashtable->table, 0, sizeof(hashtable->table));
