帮助调试 stackoverflow - 重复堆栈的后续步骤？

发布于 2024-09-26 09:24:22 字数 3241 浏览 8 评论 0原文

各位，

我的 .net 4.0 应用程序出现了堆栈溢出。使用 WinDbg，我发现以下堆栈信息块重复了 110 次（当然使用不同的内存地址），这让我相信这就是溢出的情况。问题是这些看起来都不像我的代码！关于如何进行调试有什么建议吗？

Folks,

I've got a stack overflow in my .net 4.0 app. using WinDbg I've found the following chunk of stack-info repeated 110 times (with different memory addresses of course), which leads me to believe that this is the case of the overflow. The issue is that none of this seems like my code! Any suggestions on how to proceed with debugging?

看起来您的应用程序正在递归地重新进入其 UI 消息循环。检查窗口的事件处理程序，例如在处理调整大小事件时调整窗口大小之类的事情。

It looks like your app is recursively reentering its UI message loop. Check your window's event handlers, e.g. for things like resizing the window while processing a Resize event.

我（只是）猜测这是为什么不使用 Application.DoEvents() 的一个很好的例子，但您至少应该知道是什么代码导致了这种情况。

I'm (just) guessing that this is a good example of why not to use Application.DoEvents(), but you should have at least some idea of what code causes this.
