--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
clang produces:
```
<source>:9:24: error: called object type 'std::size_t' (aka 'unsigned long') is
not a function or function pointer
9 | static_assert(false, A{});
| ^
<source>:9:24: error: called object type 'const char *' is not a function or
function pointer
9 | static_assert(false, A{});
| ^
<source>:9:24: error: the message in a static assertion must have a 'size()'
member function returning an object convertible to 'std::size_t'
```
Which explains what is going on.
