--- Comment #4 from Yann Droneaud <yann at droneaud dot fr> ---
Also with the ({}) GCC extension:
struct a {
int b;
int c;
};
void d(struct a *);
void e(void) {
struct a f = {
.b = ({
int g = 0;
g;
})
};
d(&f);
}
It produces the warning:
<source>: In function 'e':
<source>:10:17: error: missing initializer for field 'c' of 'struct a'
[-Werror=missing-field-initializers]
10 | })};
| ^
<source>:3:7: note: 'c' declared here
3 | int c;
| ^
cc1: all warnings being treated as errors
Compiler returned: 1
