Overriding a [[noreturn]] virtual function

Question

The [[noreturn]] attribute can be applied to functions that are not meant to return. For example:

[[noreturn]] void will_throw() { throw std::r         


        

Answer 1

In practice, neither g++, clang nor MSVC consider the [[noreturn]] attribute as inherited

#include 

struct B {
public:
  [[noreturn]] virtual void f() { std::cout << "B\n"; throw 0; }
};

struct D : public B {
  void f() override { std::cout << "D\n"; }
};

int main() 
{
    try { B{}.f(); } catch(...) {}
    D{}.f();

    B* d = new D{};
    d->f();
}

which prints out "B", "D" and "D" for all three compilers.
