No, GCC is correct here, according to the grammar ... or as much as you can
reason about how the grammar applies to code that doesn't conform to the
grammar.

The function declarator is `f() override` and the return type is `void()`.

You get exactly the same error without the override:

o.cc:6:5: error: ‘f’ declared as function returning a function
    6 |     void f()() { }
      |     ^~~~

That would definitely be wrong though. It's not reserved, it's "an identifier
with special meaning", and `void override() { }` is perfectly valid as a
function declaration.
