--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Created attachment 61598
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=61598&action=edit
includes the fix for libstdc++

Simplified C testcase for the ICE:
```
struct a {
  int b;
  int c;
  int d;
} e;
void f() {
  e = (struct a){};
}
```

Basically if we have a target, then using 0 is wrong, we should continue on to
the store_constructor part.
