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;}
I'd expect a few more obvious problems if this was the case, but:
are you *sure* you're compiling (and linking) against the DDImage
headers from Nuke 6.2 and not 6.1? Because Knob.h provides exactly that
doAnyHandles() declaration, so I don't understand why you declaring it
within your op would make any difference otherwise...
So your op's got no handles itself, correct? - what knobs has it got?

Peter Pearson
