It is this normalization in dxStepBody()

  // normalize the quaternion and convert it to a rotation matrix
  dNormalize4 (b->q);
  dQtoR (b->q,b->posr.R);

It means that the quaternion calculated by dxStepBody() is 0,0,0,0
Or just maybe it is trying to use NaN values?
Please put in line 254 of util.cpp the following assert macro:
  dVALIDVEC4(b->q);
And let us know if it is triggered or not.
