g++-12.0.0-alpha20210919 snapshot (g:32731fa5b0abf092029b8e2be64319b978bda514)
ICEs when compiling the following testcase, reduced from
gcc/testsuite/g++.dg/coroutines/torture/co-yield-04-complex-local-state.C, w/
-fcoroutines -fno-exceptions:

#include <coroutine>

    auto get_return_object () { return handle_type::from_promise (*this); }
    auto initial_suspend () { return suspend_always_prt {}; }
    auto final_suspend () noexcept { return suspend_always_prt {}; }
    void return_value (T);
    void unhandled_exception ();
  };

  using handle_type = std::coroutine_handle<promise_type>;

  looper (handle_type);

  struct suspend_always_prt {
    bool await_ready () noexcept;
    void await_suspend (handle_type) noexcept;
    void await_resume () noexcept;
  };
};

template <typename T>
looper<T>
