应用程序的内存布局 [英] Memory Layout of application

问题描述

以下问题是我的一个头。假设我有两个平台
具有相同的硬件，相同的操作系统和相同的编译器。如果我准确地编译
相同的应用程序，我可以确保两个机器上的内存布局将完全相同？换句话说，两个应用程序都具有相同的虚拟地址空间或
，很有可能不是这种情况。

The following question is a head-scratcher for me. Assuming that I have two platforms with an identical hardware, the same OS and the same compiler on it. If I compile exactly the same application, can I be sure that the memory layout on both machines will exactly be the same? In other words, both applications have exaclty the same virtual address space or is there a high chance that this is not the case.

感谢您的想法这个！

推荐答案

你不能指望它。作为安全功能，一些操作系统（包括Windows）在一定程度上随机化内存布局。

You can't count on it. As a security feature, some OS's (including Windows) randomize memory layout to some extent.
