--- Comment #12 from Barry Revzin <barry.revzin at gmail dot com> ---
Similar failure:

struct A {
    void f();
};

int main() {
    constexpr auto pmf =3D &A::f;
    static_assert(pmf !=3D nullptr); // error with UBSAN only
}

This surfaces from attempting to implement function_ref
(https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p0792r14.html) wh=
ich
has a constructor that takes the callable as a non-type template parameter =
and
static_asserts that it's not a null pointer.

Which apparently doesn't work with UBSAN.=
