Question

CPPUNIT在执行程序后崩溃，同时在清理阶段从main返回。 TestWrapping的dtor调用TestSuite的dtor，然后调用deleteContents来触发测试用例的清理。

有什么奇怪的是，TestSuite的dtor会被调用两次？这是在成功执行6个测试用例之后。关于如何避免这种情况的任何想法？

我希望你的代码不是显式地调用这些对象的析构函数，而是在指向它们的指针上调用delete，否则它们会超出范围而编译器会自动调用它们的析构函数。假设你没有明确地调用析构函数.....

看起来您的TestSuite对象要么执行delete this，要么它包含指向自身的指针（或者在deleteContents（）中以某种方式获取指向自身的指针）然后在该指针上调用delete 。您尚未发布TestSuite类的来源（特别是其deleteContents()方法），但这是我的猜测，没看过代码。
