Why can the the reference to the std::array be evaluated first when list-initializing it?

Running the following code

#include <array> #include <iostream> using namespace std; array<int, 2> a; array<int, 2>& f() { cout << "f" << endl; return a; } int g(int const x) { cout << "g " << x << endl; return x; } int main() { f() = { g(1), g(2) }; }

prints

f g 1 g 2

with certain configurations of g++. (Compiler Explorer)

Reading evaluation order on cppreference,

In every simple assignment expression E1 = E2 and every compound assignment expression E1 @= E2, E2 is sequenced before E1. (since C++17)

I would expect f to be printed last.

(Alternatatively, see C++ Standard [expr.assign.1].)

What am I misunderstanding?
