segmentation foult

[Jarek Rzepecki <jarekr@xxxxxxxx>]

Hi!
I have a little problem here... i'm trying to create a new class inherited
from two others. One of them in OIV class - "SoCylinder" :

class VisCyl : public SoCylinder, public TCylinder_t {
public:
  VisCyl(double r, double z);
 
};  

With constructor :

VisCyl::VisCyl(double r, double z){
  TCylinder_t("none",r,z);
  SoCylinder::radius.setValue(r);
  SoCylinder::height.setValue(z);
  
}

and then in code i call:

VisCyl *pppp = new VisCyl(2,5);

Compilation goes well. But when i run the program i got error msg :
"segmentation foult"

Lines that couses the error are:

SoCylinder::radius.setValue(r);
SoCylinder::height.setValue(z);

What am i doing wrong?
Thank you for help...
