--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
In c++ (before c++17 were the rules changed), the order of evulatating function
calls and the operator+ is not defined by the standard.
Only , (in a non argument form) causes a sequence point inside an expression
and even then you could have ordering issues still.
