I just "discovered" this bug as well. The warning works correctly in g++ 6.4,
but starting from 7.1 upwards it does not work any more.
My reproducer which is very similar:
struct Foo {
[[nodiscard]] virtual bool foo() { return true; };
virtual ~Foo() = default;
};
void shouldEmitWarning() {
auto* f = new Foo();
f->foo(); // <-- why no warning here?
delete f;
}
