Hi Peter,
this is the stack trace that I am getting:

If I do not have an viewer present the node loads up just fine; attempting to
create a viewer with this node constructed results in a similar crash.
This node implements the following functions:
bool draw_engine(int y, int ix, int r, float* buffer);
virtual void knobs (Knob_Callback);
virtual int knob_changed(Knob * k);
const char* Class() const;
const char* node_help() const;
void _validate(bool);
void append(Hash & hash);
and now, to avoid the crash:
virtual bool doAnyHandles(ViewerContext* ctx) {return false;}
Thanks for looking
Piotr

If it hasn't got any handles at all (including things like XY_knobs or
any other knob which draws its own handles), I don't think this should
be happening, as the default implementation returning false should be
enough.
Do you have a (useful) stacktrace?
