[ODE] Fw: Re[2]: ODE crashes if fdir1 vector collinear with vector of normal

   1) fdir  is in unit length
   2) I see that fdir  should be perpendicular to the contact normal,
 
  BUT:
    is it so hard to set an assert to avoid debugging without reading manual precisely?
    or to avoid such circumstances in ODE inner code even if fdir is not perpendicular.
 
   ODE declares itself a commercial equal engine, is it?
