Crash when calling constructor VWParametricObj()

Recommended Posts

I have some own plugins written in c++ which have been working without any problems. Since last update to Build 448893 my Plugins are crashing.


This is from the macOS crashreport:

Exception Type:        EXC_BAD_ACCESS (SIGSEGV)

This is the relevant code:


EObjectEvent BeamObjectEventSink::Recalculate()
	if(fhObject==NULL || VWParametricObj::IsParametricObject(fhObject)==false)return kObjectEventError;

	VWParametricObj obj( fhObject ); // This line is crashing


I have no Idea, what is wrong...

448893 is a special SDK, released by the German online update of last Monday.


(As I am not an employee of ComputerWorks, I will not tell more, esp. in public. Sorry.)

Does that mean, that there are breaking changes to the SDK during one version? Where do I get an updated SDK for that?

My direct boss @Hans Martin Kern suggests that you should contact ComputerWorks for getting that SDK.


And yes: that special SDK is not binary compatible to the regular SDK.

(The English VW still uses the regular SDK.)

Hi Nicolas,


thank you very much for your help. In the meantime I was already in contact with ComputerWorks and they sent me a link for downloading the actualized SDK. I could compile everything new and now it seems to working as expected. Ok, weekend is safe 😉
