主返回后段错误 [英] segmentation fault after main returns

问题描述

我在c在Linux的长期计划，这给了我主返回后段故障。
它是一种长的节目，所以我不能将它张贴。所以，你能帮我什么都能做这样的错误？

I have a long program in c over Linux, that gives me segmentation fault after main returns. Its a long program, so I cant post it. So can you help me what can make such error?

感谢你。

哇，这些问题的答案来的真快。谢谢大家。
我觉得我的工作了，我忘了到malloc的字符串，并用它作为缓冲。
现在，我已经malloced它，它并不意味着我一个分段错误。

Wow, Those answers came really fast. Thank you all. I think i worked it out, i forgot to malloc a string and used it as buffer. Now that I've malloced it, it does not signal me with a segmentation fault.

再一次谢谢大家。

推荐答案

猜测：所以它的返回地址丢失，你​​可能会不小心破坏了堆栈主。你有一个字符串缓冲区那里，你可能会被超越？

Guess: you might be accidentally corrupting the stack in main so it's lost the return address. Do you have a string buffer there that you could be overrunning?

如果没有，你应该试试：

If not, you should try:

• 在Valgrind的运行程序


• 用gdb调试程序赶上大跌，看看你是在这一点;您还可以调试核心文件抛投

这可能有助于安装的glibc-调试包，如果你的发行版有他们，因为你会在这一点的glibc code。

It might help to install glibc-debug packages if your distro has them since you'll be in glibc code at that point.
