'derived class' : copy constructor could not be generated because a base class copy constructor is inaccessible A copy constructor was not accessible in a base class and was therefore not generated for a derived class. Any attempt to copy an object of this type will cause a compiler error. ...
The problem is that the copy constructor is private, so the object can't be copied as happens in the normal course of handling an exception. The same applies when the copy constructor is declared explicit. C++ Copy struct S { S(); explicit S(const S &); }; int main() { throw S...
