No, because that's not even legal syntax, so that's a completely different
case.

OK, so let's change the report to say that then.
In general though, please don't report bugs claiming there are no warnings if
you haven't even tried -Wall, there's a notice when you report a bug asking you
to check that.
Reduced example:
struct A { int i; };
A f()
{
A a = { 0 };
// missing return
}
int main()
{
A a = f();
return a.i;
}
