I suspected that and ensured that I added a similar operator! to my ostream
model type, but this hadn't any impact on the outcome for that type. Further, I
don't understand how it is related to ostream initialization, because the issue
also occurs when we invert the order of the function calls:
int main() {
f2();
std::cout << "------------------\n";
f();
}
gives me:

Are you sure that this is not due to improper code generation?
