Try:

for (vtkIdType c=0 ; c < 5 ; c++)
{
   double * d = distvals->GetTuple2(c);
   std::cout << "list: " << d[0] << " , " << d[1] << std::endl;
}


I don't think that's thread-safe.  Try this instead:

for (vtkIdType c=0 ; c < 5 ; c++)
{
   double d[2];
   distvals->GetTuple(c, &d);
   std::cout << "list: " << d[0] << " , " << d[1] << std::endl;
}
