Switch to an empty buffer and enable c++-mode. Add the following content
to the buffer:

struct foo : public bar {
  foo() {}

  ~foo() {}
};

Everything is fine. Then add the keyword `override' to the destructor.

struct foo : public bar {
  foo() {}

  ~foo() override {}
};

Now ~foo is no more fontified...
