4.0读取csv的卡机问题

Cocos2d-x
#1

个人水平有限，引擎升级以后，原来的游戏频繁出现卡机问题，
错误显示

引发了异常: 读取访问权限冲突。
this->_vertexbuffer->**** 是 0xdddddddd。

查找原因最后锁定在csv->getData(xx, xx);
因为每次对白都要去在csv里寻找对白内容，现在问题是固定说几十句以后就会在固定的位置死机，请问如何解决，卡了很久，十分感谢

#2

每一次开始的对话位置不同，死机的位置也不同，但同一个对话位置肯定到同一个地方死机，不知道如何改正

#3

最好提供下demo

#4 
		sText = gk->csv_plot->getData(csv_h_num, gk->plot_text_contents);//只有这个有问题，下面的全都没有错误

gk->csv_plot的函数为

CSVReader::CSVReader()
:m_seperator(",")
, m_colLength(0)
{

}

CSVReader::~CSVReader()
{

}

demo的意思是能让我调试的小工程:joy:这看代码脑仁看疼

#6 
我发现以前CsvReader我一直用的是下面的语句
   unsigned char* pBuffer = NULL;
ssize_t bufferSize = 0;
pBuffer = FileUtils::getInstance()->getFileData(pathKey.c_str(), "rb", &bufferSize);

    4.0以后上面的不能用了，我改成了这样，然后不停的读对白的时候就会报错，下面这里是我哪里改错了吗？
unsigned char* pBuffer = NULL;
ssize_t bufferSize = 0;
Data data_gk = FileUtils::getInstance()->getDataFromFile(pathKey.c_str());
pBuffer = data_gk.takeBuffer(&bufferSize);
