[pinskia at gcc dot gnu dot org]

The following C testcase ICEs at -O2:
void g(_Complex float);
_Complex float f(int data, _Complex float x, _Complex float y)
{

        _Complex float i;
        _Complex float t, u, v;

        if (data) 
        {
                i = x +  __imag__ y;
                g(i);
        }
        else {
                v = 2;
                i = 5;
        }
        t = x + __imag__ y;
        g(t);
        u = i;
        return v * t * u;
}
