struct A {
    int a;
    A(int j) : a(j) {};
};

// non-const reference argument announces intention to change argument
void f(A& j) {j.a= 0;}

A sum(A j, A k) {return A(j.a+k.a);}

main()
{
    j= 1;            // error: undefined identifier (any error will do)
    f( A(1) );     // should get warning 11 but don't
    f( sum(A(2),A(3)) );  // should get warning 11 but don't unless
prior error
}

The last two lines in main() both deserve warning 11 "non-const reference initialized to temporary". When I compile the program only the last line gets the warning. If I fix the error on the first line of main then neither line gets a warning. This is with version 8.32.17n of the compiler and all compiler flags defaulted.
