I first applied budfix64 but it did not fix the problems. Following that, I
compiled without optimizing. THAT WORKS!
The tests of serail version all PASSED (except for the antechamber, which I
will post in a separate email). Tests of parallel version of snader and
sander.LES returned only one possible failure:
[pzq.hpc-login1 pheTI]$ more out.p1.dif
190c190
< Ewald error estimate: 0.5094E-16

Is this significant? I'd say not significant, but let me know if I am
wrong.
