--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
A simpler test:
int main()
{
static constexpr int x = 0;
static_assert(bool(&x), "");
}
ubsan.cc: In function ‘int main()’:
ubsan.cc:4:3: error: non-constant condition for static assertion
static_assert(bool(&x), "");
^~~~~~~~~~~~~
ubsan.cc:4:17: error: ‘((& x) != 0)’ is not a constant expression
static_assert(bool(&x), "");
^~~~~~~~
