You have just hit a bug.
As explained in the documentation, NWChem 6.5 does have vdw 3 parameters only for a restricted number of functionals -- and PBE96 is not one of them. Unfortunately, the code does not stops under the conditions just mentioned and keeps going, instead, with memory garbage used as vdw 3 parameters.

Here is the patch needed to prevent this erroneous behavior
