C++ SFML地牢游戏Room构造函数传入参数值损坏问题

我正在使用C++和SFML开发一款地牢爬行者游戏，编译器为gcc 6.3.0（MinGW.org GCC-6.3.0-1）。我尝试通过Room类的二维向量创建关卡布局，Room类构造函数为Room::Room(std::string layout)，布局由种子生成，每个房间种子以斜杠（/）分隔。

读取种子时，遇到斜杠就创建Room实例并加入向量。创建实例前，房间种子参数正常，但进入Room构造函数后，参数值出现损坏，指针地址也发生变化。

添加-fsanitize=address,undefined -Wall -Wextra编译参数后，出现编译警告及内部编译器错误。移除所有向量、二维数组相关调用后，构造函数仍会损坏参数，现寻求问题解决帮助。

相关代码 #

/* Get Level Layout */
layout = getLayout(level); //Calls SQLite DB
layout_dim = getLayoutDim(level); //Calls SQLite DB
rows = layout_dim[0];
cols = layout_dim[1];

std::vector<std::vector<Room*>> layout_2d(rows);

std::string acumul = "";

int current_row = 0;
int current_col = 0;

for (size_t i = 0; i < strlen(layout.c_str()); i++){
    if(layout[i] == '/'){
        Room* r = new Room(acumul);
        layout_2d[current_row][current_col] = r;

        if(current_col + 1 == cols){ //That was last column on the row
            current_row ++;
            current_col = 0;
        }
        else{
            current_col ++;
        }

        acumul = "";
    }
    else{
        acumul = acumul + layout[i];
    }
}
