--- Comment #5 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Here's another reduced version that demonstrates a regression since
r10-1280-g78f7607db4c53f:

struct base {
  virtual ~base() {}
};

struct outer : base {
  static void f();
  struct nested {
    ~nested() noexcept(noexcept(f())); // { dg-bogus "looser" }
  };
};
