I guess, it's a DI/DF problem...
If so, the code the vectorizer produces seems to be ok:
vector(2) real(kind=8) vect_cst_.14;
real(kind=8) reciptmp.5;
real(kind=4) dtime;
real(kind=8) D.1357;
...
D.1357_12 = (real(kind=8)) dtime_11(D);
reciptmp.5_60 = 1.0e+0 / D.1357_12;
...
vect_cst_.14_51 = {reciptmp.5_60, reciptmp.5_60};
VDI first shows up in ira.
