指针或堆栈溢出问题？

我甚至不确定该问什么，所以我会尽我所能解释这个问题。我到处寻找答案。无论如何，我有一个带有STM8S208C8 micro的嵌入式项目。我使用ST Visual Develop Version 4.3.5在C中开发了这个项目。下载和调试是通过ST-LINK / V2进行的，我在很多项目上已经做了很长时间，所以我认为这不是一个小问题。该项目基本上通过UART接收GPS串行消息，然后将数据转换为NMEA 2000格式的消息并发送出CAN总线。这与我多年来做过的许多项目非常相似。没什么特别的。现在的问题是，在随机时间（几分钟到几小时），程序将飞离，永远不会降落。此时，中断仍然存在，但程序执行在某处。这看起来像你的标准日常指针损坏或堆栈溢出问题，但我找不到根本原因是不成功的。我希望有人能提出一个很好的技巧来找到这个问题。您需要的任何细节，请问。非常感谢您提供任何帮助。

I'm not even sure what to ask so I'll explain the problem as best I can. I did search everywhere for an answer. Anyway, I have an embedded project with a STM8S208C8 micro. I developed the project in C using ST Visual Develop Version 4.3.5. Down load and debug is via ST-LINK/V2 which I have been doing for a very long time on multiple projects so I do not think this is a trivial problem. The project basically receives GPS serial messages via the UART then translates the data into NMEA 2000 formatted messages and sends out the CAN bus. This is very similar to many many projects I have done over the years. Nothing special to me. Now the problem is that at random times (minutes to hours) the program will fly off to never never land. At that point, interrupts still come in but the program execution is way out somewhere. This looks like your standard everyday pointer corruption or stack overflow problem but I have been unsuccessful in finding the root cause. I would love someone to suggest a good technique in locating this problem. Any details you need, just ask. Thank you very much in advance for any help at all.
