调试'在抛出...的实例后调用终止',当异常_should_被捕获时

Question

调试'在抛出...的实例后调用终止',当异常_should_被捕获时

我正在调试一个似乎只在Solaris上发生的问题(我们在Windows,Linux,OSX,Solaris,HP-UX和AIX上进行测试).

我们的代码抛出一个异常(完全可以预料到),这会导致打印'抛出一个......实例后调用终止',并终止进程.

Simba::Support::ErrorException 是消息抱怨的类型,我们都在ConnectionAttributes.cpp 299线扔它的一个实例,但据我所知,这不应该造成的std ::终止()被抛出,因为:

据我所知,在由先前异常提示的堆栈展开期间,这不是从析构函数抛出的(我在跟踪异常类型的构造函数中添加了跟踪,并且它只在崩溃之前调用了一次)
当前线程的堆栈至少有一个框架上有一个框架catch (Simba::Support::ErrorException&)(同一框架也有一个框架catch (...),只是为了确定),其上可能还有其他应该捕获异常的框架.

还有什么其他原因呢？我错过了我的逻辑吗？

鉴于它只发生在Solaris上,我在运行时考虑一些问题？

如果要创建由非 C++ 可执行文件加载的 C++ 共享对象，则需要确保 C++ 共享对象对正确的 C++ 运行时库具有动态依赖关系。

使用 C 可执行文件加载的 C++ 共享对象不依赖于该libstdc++.so共享对象。

生成一个 C++ 共享对象，而不动态依赖于libstdc++.so. 另外，请注意，尽管存在-static-libgcc争论，但仍然存在动态依赖性libgcc_s.so：

libgcc_s.so.1 =>         /opt/csw/lib/libgcc_s.so.1

这可能是因为libicudata_sb32.so、libicui18n_sb32.so和/或中的一个或全部以需要动态的libicuuc_sb32.so方式链接。请参阅使用 -static-libgcc 和 -static-libstdc++ 编译 libconfig++，以获取其中问题的示例，并且仍然生成动态依赖于这些库的共享对象版本的二进制文件。libgcc-static-libgcc-static-libstdc++

用于加载此共享对象的 C 二进制文件链接到

这不会也不应该导致对的任何依赖libstdc++.so。

并参阅静态链接 libstdc++：有任何问题吗？仅针对一个有关libstdc++静态链接的潜在问题的问题。请注意，即使这个问题也只是涉及将一个副本静态链接libstdc++到可执行文件中。静态链接libstdc++到共享对象会引发各种其他问题：每个喜欢的 C++ 共享对象是否都能正确访问以这种方式链接的 C++ 运行时的一份副本？或者您是否要静态链接到libstdc++进程可能加载的每个 C++ 共享对象的多个副本？那项工作做得怎么样？如果开始出现奇怪的问题，您将如何开始调试它们？

如果非 C++ 可执行文件动态加载 C++ 共享对象并在libstdc++其中包含静态副本，然后该可执行文件动态链接到另一个动态依赖于的 C++ 共享对象，会发生什么情况libstdc++.so？libstdc++.so如果在静态副本已加载并初始化后加载C++ 运行时的动态副本，会发生什么情况？如果颠倒顺序会发生什么？如果升级更改了libstdc++.so，但您没有提供的静态链接副本的更新副本，会发生什么情况libstdc++？

底线是：如果您正在创建需要由非 C++ 可执行文件加载的 C++ 共享对象，并且不想处理上面列出的所有潜在问题，则需要正确记录对 C++ 的动态依赖项所有 C++ 共享对象中的运行时。

你需要添加类似的东西
