struct Point
{
    float _x, _y;

    void rotateCCW()
    {
        float tmp = -_x;
        _x = _y;
        _y = tmp;
    }
}

Compile this struct with -O.
findreg(x0, line=660, file='backend/cod4.c')
Internal error: backend/cgcod.c 1178

This is probably again an effect of painting -x as integral in eleq
and later trying to assign it to an XMM reg.
