This seems fixed in GCC 11+, maybe by the patch which fixed PR 41437.

This can also be triggered on gcc 9 using
```
class A
{
int foo() const { return 42; }
};

template
struct B : public A
{
static constexpr auto member_fn = &B::foo;
};

int main()
{
return (A().*B<>::member_fn)();
}
```

running `g++ -std=c++17 -O2 -Wall -Wextra` produces
main:
mov eax, 42
ret
