Bug#322218: more robust code (gcc -O2 optimization bug)

Hi, in floating point code is better to avoid testing with equality. In your example, you should change if (fa == 0.0) if (fb == 0.0) into: if (fabs(fa) < DBL_EPSILON) if (fabs(fb) < DBL_EPSILON) After that, it works with gcc -O2. Regards Petr -- To UNSUBSCRIBE, email t
