Totally understandable. Thanks for following up on this.

Can you check this case with your build?
```cpp
struct A { int x; };

char q(int *);
short q(int A::*);

template <typename T>
constexpr int f(char (*)[sizeof(q(&T::x))]) { return 1; }

template <typename T>
constexpr int f(char (*)[sizeof(q(&(T::x)))]) { return 2; }

constexpr int g(char (*p)[sizeof(char)] = 0) { return f<A>(p); }
constexpr int h(char (*p)[sizeof(short)] = 0) { return f<A>(p); }

static_assert(g() == 2);
static_assert(h() == 1);
```
