任何人都可以帮助我吗？我遇到了与内存泄漏有关的问题。我不知道如何解决它，任何人都可以提出一些建议，我们将不胜感激。

以下是有关我的代码的一些信息。我创建了一个名为struct的{{1}}和一个名为ObjectData的{{1}}，如下所示：

class

以下是ObjectLoader和struct ObjectData { std::vector <glm::vec3> vertices, normals, colors; std::vector <glm::vec2> texCoords; std::vector <unsigned int> vIndices, uIndices, nIndices; }; class ObjectLoader { private: std::tr1::shared_ptr<ObjectData> object; bool hasUV, hasNormals, hasColor, colorChecked, indexChecked; std::string parseString(std::string src, std::string code); std::vector<glm::vec3> parseVerColor(std::string src, std::string code); glm::vec2 parseVec2(std::string src, std::string code); glm::vec3 parseVec3(std::string src, std::string code); void addIndices(std::string str); void checkIndices(std::string str); void checkColors(std::string str); void loadObjects(std::string objPath); public: ObjectLoader(std::string objName); ~ObjectLoader(); std::tr1::shared_ptr<ObjectData> getModel(); };实施代码：

getModel()

当我测试我的代码时，我遇到了与内存泄漏有关的问题。

这是我的测试代码：

ObjectLoader()

Answer 1

由于std::shared_ptr。

的范围，您在检测泄漏时遇到问题

在代码中;

std::tr1::shared_ptr<ObjectLoader> loader = std::tr1::shared_ptr<ObjectLoader>(new ObjectLoader(fileName));
std::tr1::shared_ptr<ObjectData> data = loader->getModel();
_CrtDumpMemoryLeaks();

loader和data析构函数以及删除操作直到_CrtDumpMemoryLeaks();函数报告泄漏后才会运行。

添加额外的范围可以帮助解决这个问题，否则代码需要重新构建。

{
    std::tr1::shared_ptr<ObjectLoader> loader = std::tr1::shared_ptr<ObjectLoader>(new ObjectLoader(fileName));
    std::tr1::shared_ptr<ObjectData> data = loader->getModel();
} // destructors run here...
_CrtDumpMemoryLeaks();

使用shared_ptr时内存泄漏
