我在 C++ Builder 2010 项目中低于 EAccessViolation 异常。
StackTrace 没有在其中显示我的任何项目文件。如何找到错误的位置？此应用程序使用 TIdTCPServer 组件。

调用堆栈信息：

这应该是损坏的内存或指针。这不会很容易调试，您需要验证您使用的所有指针都具有正确的值，并且您不会在任何地方越界。

从以下网址下载最新版本的 FastMM：http: //sourceforge.net/projects/fastmm/files/FastMM%204.x%20Stable%20Releases/

在 c++builder 中安装它。
阅读文档如何在 FastMM 中设置调试模式。
如果你有悬空指针或写入禁忌位置，FastMM 应该很快就能找到它们。

祝你好运。

（请注意，包含了一个更简单的 FastMM 版本，但这个版本更深入）
