[ODE] Problem with slider joint and dQuickStep

I'm was trying dWorldQuickStep and dWorldStep to see what is the speed
of the 2 stepper function. I found the dWorldQuickstep stepper to be
unusable since the body A and B (see ascii figure below) start to
wobble. The other bodies are stable.
When I use dWorldStep there is no problem.
I don't know if anybody experienced this kind of problem with a slider.
I'm using revision 991 (out of svn less than a month ago so the patch
slider is included).
When I define or undefined dGYROSCOPIC there is no difference.
So do you have any hint of where should I look or what should I do.
Capital letters are bodies
Number are joints
G and A attached by Hinge at 1
A and B attached by Slider at 2
B and C attached by Ball at 3
F and C attached by Ball at 3 (There is 2 ball joints at 3)
C and D attached by Ball at 4
D and E attached by Hinge at 5
E and F attached by Ball at 6
E and G attached by Hinge at 7

N.B. You can see the mechanism as the boom of a Wheel Loader where
D is the bucket and G is the body of the Wheel Loader and
A,B is the piston and C,F,E are different links.
