Несколько неопозиционных модификаций после оценки аргумента - определенного или неопределенного поведения? ⇐ C++

[Anonymous]

The standard states that the behavior of unsequenced operations that have side effect on the same memory location is undefined [intro.execution§10].
Does the following code have undefined behavior, for having multiple unsequenced side effects on the variable sid, through the unsequenced call to bar in main:

Код: Выделить всё

int bar() {
static int sid;
return ++sid;
}

void foo(int i1, int i2) {
std::cout
