segmentation foult...

[Jaroslaw Rzepecki <jarekr@xxxxxxxxxxxxxxxxx>]

Hi!
  I have a problem with defining an SoClipPlane... Below you can see a
piece of my code:
   
   SbVec3f *P1 = new SbVec3f();
   SbVec3f *P2 = new SbVec3f();
   SbVec3f *P3 = new SbVec3f();

   P1->setValue(1,1,1);
   P2->setValue(3,1,1);
   P3->setValue(2,1,4);

   SbPlane Plaszcz(*P1,*P2,*P3);
   SoClipPlane *ClipPlaszcz = new SoClipPlane();
   ClipPlaszcz->plane.setValue(Plaszcz);

it compiles well. Hovewer while running (and debuging) i get a 
segmentation foult error at:  
        
   ClipPlaszcz->plane.setValue(Plaszcz);

What am I doeing wrong?
Thank you for help
