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

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
