大量内存泄露信息

[fasiondog]

bug描述 Describe the Bug

客户程序在使用 2.3.0、2.3.1 版本的 paddle 时，如果自身编译时进行内存泄露检测，在程序退出时 paddle 会报大量的内存泄露信息，也许是因为 paddle 全局变量的原因也许是真的存在内存泄露，大量的泄露信息导致调用 paddle 的程序无法观察到自身有用的泄露信息
1、如果是paddle存在内存泄露，建议解决并在自动测试时附加内存泄露检测
2、如果是paddle全局变量不释放的原因，建议提供清除paddle全局变量的相关方法，以便使用者不被大量的泄露信息淹没

运行 Paddle-Inference-Demo/c++/cpu/resnet50 实例使用 “-fsanitize=address -fsanitize=leak” 进行编译时内存泄露检测

运行输出如下：

补充下，2.1.1 版本不存在这些内存泄露信息

[wanghuancoder]

感谢您的反馈！我让预测相关研发同学研究一下您的这种情况。

[jiweibo]

这个看起来是误报，paddle注册的operator、kernel等都是static的，要等进程退出前才会释放。
可以用gperftools或者长时间运行的方式检查内存泄露。

不可能靠长时间运行这种方式来检查内存泄露，还是测试时就把可能的检测点覆盖，有没有泄露，测试完立刻就知道了。
