VLD

代码

Release版本下检测内存泄漏配置

#define VLD_FORCE_ENABLE
#include <vld.h>
#pragma comment(lib, "vld.lib")
int main()
{
    VLDGlobalEnable();
    VLDReportLeaks();
    int* p = new int;
    VLDGlobalDisable();
}

结果

Dr. Memory

配置

对于 Visual Studio，选择Tools | External Tools...菜单选项以打开“外部工具”对话框。单击添加并填写如下字段（drmemory.exe如果您将其安装在其他位置，请调整路径）

Title: Dr. Memory
Command: C:\Program Files (x86)\Dr. Memory\bin\drmemory.exe
Arguments: -visual_studio -- $(TargetPath)
Initial Directory: $(TargetDir)

代码

int main()
{
    int* p = new int;
}

运行

现在可以选择Tools | Dr. Memory，Visual Studio 将运行应用程序。Dr. Memory 的输出（连同程序）将打印到输出窗口。可以双击任何调用堆栈框架上的源文件，以便自动打开该文件到指定的行号。

结果
