Summary0013100: Crash in MeshVS with large meshes
DescriptionApplication (OMF sample) crashes during NASTRAN file import. The file used:
\\aquarex\nnt_03\RINA\Data\Mod291K_V90.dat.

The problem is in ros/src/MeshVS/MeshVS_TwoNodes.cxx, in method Hash(). When the
node IDs are big enough, their multiplication can overflow the result and return
a negative hash code.

For the solution, I suggest to use the sum of IDs rather than their product.
