我得到这个错误：“glibc detected” [英] I get this error: "glibc detected"

问题描述

我刚刚写了一段CPP代码，我在Ubuntu中使用G ++编译它。
当我运行我的代码一切都很好，代码运行良好，并给出输出，但不退出，并给出此错误：

I just wrote a piece of CPP code and I compiled it using G++ in ubuntu. When I run my code everything is fine, the code runs well and gives output but doesn't exit and it gives this error:

这个意思？我怎么能摆脱它？
我不使用malloc或free，我只是使用向量！

What does this mean? How can i get rid of it? I'm not using malloc or free , I'm just using vector!

推荐答案

不直接分配内存，它发生在向量代码，你很可能通过编写你不应该的内存损坏一部分内存。我可以想到的最可能的原因是：

Even if you're not allocating memory directly, it happens under the hood in vector code and you most likely corrupted some portion of memory by writing where you are not supposed to. The most likely reasons I can think of are:

1. 写入超出范围的元素


2. 使用指针/对不再有效的元素的引用 - 请注意，插入更多元素可能会使以前的引用无效

当然，我不能肯定地说，除非你发布一些相关的代码。或尝试使用 valgrind 查找问题的根源。

Of course, I can't say for sure unless you post some relevant code. Or try using valgrind to find the source of the problem.
