Query result for vectorization_short_regress.q.out -- that is when vectorization is turned off and a base .q.out file created.

-----------------------------------------------

10th field of the query below: Non-Vectorized -6432.000015344526 vs. Vectorized -6432.0

Column expression is (-(cdouble)) as c4,
