in hiredis.d
------------------------
struct redisReply {
    int type; /* REDIS_REPLY_* */
    int integer; /* The integer when type is REDIS_REPLY_INTEGER */
    int len; /* Length of string */
    char* str; /* Used for both REDIS_REPLY_ERROR and REDIS_REPLY_STRING */
    size_t elements; /* number of elements, for REDIS_REPLY_ARRAY */
    redisReply** element; /* elements vector for REDIS_REPLY_ARRAY */
};
------------------------

but in hiredis.h
------------------------
typedef struct redisReply {
    int type; /* REDIS_REPLY_* */
    long long integer; /* The integer when type is REDIS_REPLY_INTEGER */
    int len; /* Length of string */
    char *str; /* Used for both REDIS_REPLY_ERROR and REDIS_REPLY_STRING */
    size_t elements; /* number of elements, for REDIS_REPLY_ARRAY */
    struct redisReply **element; /* elements vector for REDIS_REPLY_ARRAY */
} redisReply;
------------------------

So you have "int integer;" in D and "long long integer;" in C, which doesn't 
match. I'm not sure what size "long long" is in C, but I guess you need 
"long" in D?
