            Bug ID: 49321
           Summary: forming reference to nullptr is not rejected in
                    constexpr
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++2a
          Assignee: unassignedclangb...@nondot.org

I think this UB should be rejected.

```
constexpr bool foo(int* i) {
    int& j = *i;
    return true;
}

static_assert(foo(nullptr));
```
