[vtkusers] Crashed on vtkDataArray::SetName(...)

[Weiguang Guan]

I used vtk 5.0.4. I've found that in vtkDataArray.h
 	virtual void   SetNumberOfTuples (vtkIdType number)=0
But this pure virtual function is never defined in vtkFloatArray.h. How 
could that be possbile!!! Why doesn't c++ compiler complain about this? 
I'm confused!
