单元测试，内存报错（memory access violation...）我是新手，求大神们指点！！

[shawn_cd]

这是部分代码，不知错怎么改
//--------------------testing file
BOOST_TEST_MESSAGE("class Notify unit testing...");
{
Notify str1,str2;
std::vector<uint8_t> v1,v2;
str1.pack(v1);
std::pair<std::vector<uint8_t>*,size_t> data=std::make_pair(&v1,0);
str2.unpack(data);//这句测出的错
str2.pack(v2);
BOOST_CHECK(v1==v2);

}

//-------------------------------------------
//.cpp
void Notify::pack(std::vector<uint8_t>& buf)
{
if(requestIdList)//class RequestIDList:public ObjectContainer<std::shared_ptr<RequestParametersObject>>
requestIdList->pack(buf);
if(notificationList)
notificationList->pack(buf);
}

void Notify::unpack(std::pair<std::vector<uint8_t>*,size_t>& data)
{
auto buf = *data.first;
size_t bufSize = buf.size();
Object::Header *hdr = Object::getHdr(buf, data.second);

if(!requestIdList)
requestIdList.reset(new RequestIDList);
requestIdList->unpack(data);
if(!notificationList)
notificationList.reset(new NotificationList);
notificationList->unpack(data);
}

//-------------------------------------------
//---------------.hpp
class RequestIDList:public ObjectContainer<std::shared_ptr<RequestParametersObject>>
{
public:
RequestIDList() {};
~RequestIDList() {};
size_t length();
void pack(std::vector<uint8_t>& buf);
void unpack(std::pair<std::vector<uint8_t>*,size_t>& data);
};

struct Notify
{
public:
std::shared_ptr<RequestIDList> requestIdList;
std::shared_ptr<NotificationList> notificationList;

void pack(std::vector<uint8_t>& buf);
void unpack(std::pair<std::vector<uint8_t>*,size_t>& data);
size_t size();
Notify();
~Notify();
};

调试，确定哪句出错

[luciferisnotsatan]

单步调试下

[三文鱼也会飞]

requestIdList.reset(new RequestIDList);
requestIdList->unpack(data);


1 感觉应该是先unpack后reset
2 new RequestIDList是栈区开辟内存，函数结束就释放了，你却没有delete

[shawn_cd]

应该所Notify::unpack（）函数出了错，但我不知道错在哪，内存错太麻烦了

[至善者善之敌]

memory access violation原因很可能 使用了没有被创建或者已经被释放的对象

楼主在仔细看看
