What is the meaning of this C++ Error std::length_error
提问by Janusz
While running my program I get this error:
在运行我的程序时，我收到此错误：
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_S_create
Abort trap
I know that you can't do much without the code but I think that this error is too deep in the code to copy all of it. Maybe I can figure it out if I understand what this error means. Is this a sign for an issue with reading or writing at the wrong memory address?
我知道没有代码你就无能为力，但我认为这个错误在代码中太深了，无法复制所有内容。如果我理解这个错误的含义，也许我可以弄清楚。这是在错误的内存地址读取或写入问题的迹象吗？
Is there something I can do to get more information about the problem from my program?
我可以做些什么来从我的程序中获取有关问题的更多信息？

I know this is a old question but I just ran into the same issue. Using Linux with gcc.
我知道这是一个老问题，但我遇到了同样的问题。使用带有 gcc 的 Linux。
Disassembling the function showed a lot of jumps in the code, where the exception was thrown, which shouldn't be there. In the end, a Clean Build resolved the issue for me.
反汇编函数显示代码中有很多跳转，抛出异常的地方不应该存在。最后，Clean Build 为我解决了这个问题。

This is an error in debug mode with VS2005. When I change it to release mode, everything works.
这是 VS2005 调试模式下的错误。当我将其更改为发布模式时，一切正常。
Well, the vc debug runtime causes this, that's all.
好吧，vc 调试运行时导致了这个，仅此而已。
