What is this? http://www.beholdgenealogy.com/img/ideexception.gif
这只是偶尔发生，但按OK后，我的IDE和程序都可能冻结。如果我很幸运，我有时可以在Delphi中做一个File / SaveAll，但有时我不能。无论哪种方式我都被卡住，那么我唯一可以做的就是使用Windows任务管理器关闭Delphi。当然，如果我无法SaveAll，那么我失去了自上次保存以来所做的所有编辑。
我已经安装了包括Update 4在内的所有Delphi 2009更新。我还安装了IDE Fix Pack 2009 2.9。
该错误被EurekaLog困扰我，错误报告提供以下调用堆栈：

正如你所看到的，所有的调用堆栈都在Delphi和Windows中。它没有连接回我的程序中的任何行。
我看过网页：External Exception EEFFACE并将其从德语翻译成英文，但似乎在谈论Delphi C，而我根本不使用C。
我的问题是，我不知道可能导致这一点，因为它不会一直发生。我不知道甚至在哪里寻找它或如何跟踪它。
有人知道这是什么，如何跟踪它，或至少阻止它发生？
EurekaLog的Alex发布了这个响应my query on their forum：
I think it may be a bug in Delphi’s
debugger. Possibly related to
evaluation tooltips or something
similar.See for yourself – we have an C++
exception in system module (EEFFACE is
a special code for VCL exception. When
VCL encounters an unknown C++
exception – it wraps it into
EExternalException object with code =
EEFFACE) and call stack includes
Delphi debugger’s units:

I think that you should post this
description to Embarcadero’s Quality
Central.Try to disable “IDE integration”
check-Box (it’s located in IDE’s
“EurekaLog”/”EurekaLog IDE Options”
menu) and run your application – see
if there will be a change in behavior.
现在我向Quality Central递交了一份报告：
http://qc.embarcadero.com/wc/qcmain.aspx?d=81881
希望通过这些信息，Embarcadero可以在将来的版本中防止这种情况。
4年后我回到这个问题，并意识到，在几个月前，我找到了解决方案，所以我在这里发贴给任何可能遇到这个问题的人。
问题和解决方案在Olaf Monien的博客中提供，在2009/07/22的一篇名为Delphi 2009 / Windows 7/64位调试器崩溃解决方案的文章中。
奥拉夫关于这个职位的指示对我来说是完美的，问题已经消失了。我感谢他对他的博文发表评论。
正如@rossmcm在他的评论中指出的那样，Olaf的博文不再在那里，而是the post can still be found on the Internet Archive.相反，请查看Chris Miller’s information about the problem，其中包括the patch tool that now has a permanent home at Embarcadero的链接。
解决方法
EEFFACE是C使用的SEH异常代码，它是“泄漏”到一些Delphi代码(在这种情况下是IDE本身)。当异常代码不是Delphi生成的异常或与硬件相关的异常时，Delphi会将其映射到EExternalException。
