试图从堆中释放内存时，Project.exe触发了一个断点

问题描述

typedef struct Room
{
    int     number;             //the room number
    float   cost_for_night;     //how much does the room cost per night?
    int     available;          //is the room available now?
    char* type;             //room type - free text
} Room;

Room* CreateNewRoom(int _number,float _cost,int _available,const char* _type)
{
    // create new room with the data we got as varibales
    struct Room* r = (struct Room*)malloc(sizeof(struct Room)); // try allocate memory for the room pointer
    if (r == NULL)
    {
        // if failed,release the memory and return null
        free(r);
        return NULL;
    }
    r->type = (char*)malloc((strlen(_type) + 1) * sizeof(char)); // try allocate memory for the type pointer
    if (r->type == NULL)
    {
        // if failed,release the memory and return null
        free(r->type);
        free(r);
        return NULL;
    }
    // if seceeded,fill the room with the data from the user
    r->number = _number;
    r->cost_for_night = _cost;
    r->available = _available;
    strcpy_s(r->type,strlen(_type) + 1,_type);
    return r; // return the room
}

void FreeRoom(Room* rm)
{
    free((*rm).type);
    free(rm);
}

我正在尝试从堆中释放内存，但是每次我尝试释放房间类型时，它都达到了一个断点。 我已经放置了Room的结构，我添加了一个具有CreateRoom功能的新房间，最后尝试释放内存。
