Looks like a typo in min/brent.c.  You should be compare bounds on both 
ends with
the new position:

        d = p / q;
        u = z + d;

!       if ((u - x_left) < t2 || (x_right - u) < t2)
          {
            d = (z < midpoint) ? tolerance : -tolerance ;
          }
--- 132,138 ----
        d = p / q;
        u = z + d;

!       if ((u - x_left) < t2 || (x_right - z) < t2)
          {
            d = (z < midpoint) ? tolerance : -tolerance ;
          }


Is this correct?
