GCC 7-13 does:
```
<source>:17:24: in constexpr expansion of 'fn7(0, 0)'
<source>:17:43: error: dereferencing a null pointer
constexpr int n3 = fn7 ((const int *) 0, 0);
^
<source>:18:24: in constexpr expansion of 'fn7(0, 8)'
<source>:18:43: error: dereferencing a null pointer
constexpr int n4 = fn7 ((const int *) 0, 8);
^
```
While the trunk gives:
```
<source>:17:24: in 'constexpr' expansion of 'fn7(0, 0)'
<source>:14:14: error: dereferencing a null pointer
14 | return fn6 (*a, b);
| ~~~~^~~~~~~
<source>:18:24: in 'constexpr' expansion of 'fn7(0, 8)'
<source>:14:14: error: dereferencing a null pointer
```
Which seems like the correct location now.

So I guess fixed.
