我正在检查我的代码是否存在内存泄漏。在我得到代码之前一切都很好：
mSystem = new LightSystem();
sf::View *view = th::DisplayManager::Get()->GetCamera();
mSystem->SetView(*view);
SetView确实很小的工作（提取传递的view指针的一些成员。当最新的代码行被注释时，一切都很好，但是取消注释一切都在默认模式下工作，并且在使用 valgrind（valgrind --tool=memcheck ./Binary）进行内存泄漏检测时失败。

问题是：为什么在没有 valgrind 的情况下它可以成功运行并打破它。我也尝试设置--main-stacksize=一个很大的值，但它对我没有帮助。
