Delphi中的外部异常EEFFACE

Delphi中的外部异常EEFFACE

lke*_*ler 19 ide delphi exception delphi-2009

在使用Delphi 2009调试我的应用程序时,我有时会发生以下异常:

这是什么？http://www.beholdgenealogy.com/img/ideexception.gif

这只是偶尔发生,但在按下OK之后,我的IDE和程序都可能会冻结.如果我很幸运,我有时可以在Delphi中进行File/SaveAll,但有时候我不能.无论哪种方式我都被卡住,然后我唯一能做的就是使用Windows任务管理器来关闭Delphi.当然,如果我无法SaveAll,那么我将丢失自上次保存以来所做的所有编辑.

我安装了所有Delphi 2009更新,包括Update 4.我还安装了IDE Fix Pack 2009 2.9.

EurekaLog为我捕获了错误,错误报告给出了以下调用堆栈:

如您所见,所有调用堆栈都在Delphi和Windows中.它根本不连接到程序中的任何行.

我查看了网页:外部异常EEFFACE并将其从德语翻译成英语,但它似乎是在谈论Delphi C++,而我根本不使用C++.

我的问题是我不知道是什么导致这种情况,因为它不会一直发生.我甚至不知道在哪里寻找它或如何追踪它.

有人知道这是什么以及我如何追踪它或至少阻止它发生？

EurekaLog的Alex发布了这个以回应我在他们论坛上的查询:

我认为这可能是Delphi调试器中的一个错误.可能与评估工具提示或类似的东西有关.

亲自看看 - 我们在系统模块中有一个C++异常(EEFFACE是VCL异常的特殊代码.当VCL遇到未知的C++异常时 - 它将它包装到代码= EEFFACE的EExternalException对象中)并且调用堆栈包括Delphi调试器的单元:

我认为您应该将此描述发布到Embarcadero的Quality Central.

尝试禁用"IDE集成"复选框(它位于IDE的"EurekaLog"/"EurekaLog IDE选项"菜单中)并运行您的应用程序 - 查看行为是否会发生变化.

我现在已经向Quality Central提交了一份报告:

http://qc.embarcadero.com/wc/qcmain.aspx?d=81881

希望通过这些信息,Embarcadero将能够在未来的版本中防止这种情况发生.

4年后我回到这个问题,并意识到几个月前,我找到了解决方案,所以我在这里发布给其他可能遇到此问题的人.

问题和解决方案在Olaf Monien的博客中提供,在2009/07/22的帖子中标题为Delphi 2009/Windows 7/64 bit Debugger Crash Workaround.

奥拉夫对那篇文章的指示对我来说非常有效,问题就不复存在了.我在评论他的博客文章时感谢他.

正如@rossmcm在他的评论中指出的那样,奥拉夫的博客文章不再存在,但该帖子仍然可以在互联网档案馆找到.相反,请查看Chris Miller关于该问题的信息,其中包括现在在Embarcadero拥有永久住所的补丁工具的链接.

这显然是Delphi评估器(它是编译器的一部分)中发生的事情.奇怪的是,如果它实际上是通过writeobj.c,那肯定是不对的.如果您可以使用测试用例重现此问题,请在QualityCentral(http://qc.embarcadero.com)中报告.

EEFFACE是C++使用的SEH异常代码,它正在"泄漏"到某些Delphi代码(在本例中为IDE本身).当异常代码不是Delphi生成的异常或硬件相关异常时,Delphi只是将其映射到EExternalException.

关于"解释有效负载":前段时间我写了一个这样的Delphi包装类,它模仿C++ RTL中的一些函数,并使用它们来提取异常类型名称,在std :: exception的情况下,使用异常消息由std :: exception :: what()返回.它还提供对实际C++异常对象的访问,以便C++ Builder代码可以在TApplicationEvents :: OnException处理程序中执行动态异常分派.您可以在http://www.audacia-software.de/en/win/bcb/sc.htm#SystemCppException找到我的包装器. (3认同)
