It still fails if we make S a template:
template <int> struct A;
template <typename T> struct B : A<sizeof(T)> {};
template <typename F>
B<typename F::type> operator-(F);
template <typename T>
struct S
{
struct F
{
typedef S type;
};
auto foo() -> decltype(-F());
};
int main()
{
S<int> s;
}
test.cpp: In instantiation of 'struct B<S<int> >':
test.cpp:16:28: required from 'struct S<int>'
test.cpp:21:12: required from here
test.cpp:3:42: error: invalid application of 'sizeof' to incomplete type
'S<int>'
template <typename T> struct B : A<sizeof(T)> {};
^
Tested with r197837.
