[vtkusers] syntax question

[A J]

Actually just before it ccrashes it shows these errors:

Creating an array of Stuff
Hello World in B Class!
hello world completed
     15781:     symbol=_ZN24vtkSimpleCriticalSectionD1Ev;  lookup in 
file=runit
     15781:     symbol=_ZN24vtkSimpleCriticalSectionD1Ev;  lookup in 
file=/usr/local/src/vtk/vtkbin/bin/libvtkAtamaiTracking.so
     15781:     symbol=_ZN24vtkSimpleCriticalSectionD1Ev;  lookup in 
file=/usr/local/src/vtk/vtkbin/bin/libvtkCommon.so
Segmentation fault (core dumped)


..which is weired..??  Im not even using these classes...!

Can someone try doing

        vtkBclass **Stuff;
	for (int i=0; i<20; i++)
		Stuff[i] = vtkBclass::New();

	Stuff[5]->HelloWorld();

or something similar and see if it works or crashes for them..?

Thanks!!
