--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So this `( X0 && ) { } ` is a compound-literal which is invalid in C++ in the
first place so this is an extension.
GCC basically does this like `(X0 &&) X0{ }` which is in more tune like C99
compound-literal (though it is a temporary).
GCC rejects the original testcase with -pedantic-errors:
```
<source>:1:32: error: ISO C++ forbids compound-literals [-Wpedantic]
1 | struct X0 { } X1 = ( X0 && ) { } ;
| ^
```
Note this is accepted by both compilers:
```
struct X0 { } X1 = ( X0 && ) X0{ } ;
```
Basically the extension is implemented slightly different by both compilers
that is fine since it is an extension to the language.
