<pre>This code:
class Base
{
virtual ~Base() = default;
};
class Derived : public Base
{
~Derived() override = default;
};
Produces this nonsensical error:
main.cpp:9:5: error: deleted function '~Derived' cannot override a non-deleted
function
~Derived() override = default;
^
main.cpp:4:13: note: overridden virtual function is here
virtual ~Base() = default;
^
1 error generated.
This is just plain wrong. GCC accepts this code. Override is possible on a
virtual destructor, and is a useful tool to actually detect if the destructor
of inherited classes is properly virtual (although the check only goes one
level deep).</pre>
