Exception for Octave 3.8, jcobi/3

\[\alpha \gt -1 \land \beta \gt -1\]

Math

\[\frac{\frac{\frac{\left(\left(\alpha + \beta\right) + \beta \cdot \alpha\right) + 1}{\left(\alpha + \beta\right) + 2 \cdot 1}}{\left(\alpha + \beta\right) + 2 \cdot 1}}{\left(\left(\alpha + \beta\right) + 2 \cdot 1\right) + 1}\]

C

double f(double alpha, double beta) {
        double r8652 = alpha;
        double r8653 = beta;
        double r8654 = r8652 + r8653;
        double r8655 = r8653 * r8652;

        double r8658 = r8656 + r8657;
        double r8659 = 2.0;
        double r8660 = r8659 * r8657;
