如何结束一个指向0xCCCCCCCC的指针

问题描述

我正在处理崩溃的程序有时尝试读取地址 0xCCCCCCCC 的数据。 Google（和StackOverflow）是我的朋友，我看到它是未初始化的堆栈变量的MSVC调试代码。为了理解问题来自哪里，我试图重现这种行为：问题是我不能这样做。

问题是：你有一个代码显示指针如何结束指向 0xCCCCCCCC ？

谢谢。

解决方案

使用或。请确保也用于禁用任何优化。 / p>

The program I'm working on crashes sometimes trying to read data at the address 0xCCCCCCCC. Google (and StackOverflow) being my friends I saw that it's the MSVC debug code for uninitialized stack variable. To understand where the problem can come from, I tried to reproduce this behavior: problem is I haven't been able to do it.

Question is: have you a code snippet showing how a pointer can end pointing to 0xCCCCCCCC?

Thanks.

解决方案

Compile your code with the /GZ compiler switch or /RTCs switch. Make sure that /Od switch is also used to disable any optimizations.
