crash around ACAPI_3D_GetCurrentWindowSight

[Anonymous]

Hi, guys.

There is something strange occurs in my add-on. I am quite sure the crash happens around ACAPI_3D_GetCurrentWindowSight when it is called for its 3rd time.

I was wondering if the destructor of Modeler::SightPtr itself releases the space created before so I have to create Modeler::SightPtr on the heap rather than stack?

Here is my code:

	AttributeReader attrReader; 
	ModelerAPI::Model model;

	Modeler::SightPtr currentSightPtr;

	GSErrCode sightErr = ACAPI_3D_GetCurrentWindowSight((void**)&currentSightPtr);
	if (sightErr != NoError) {
		return APIERR_CANCEL;
	}

	EXPGetModel(currentSightPtr, &model, &attrReader);

Could anyone help me please? Thanks in advance.

Maybe I have solved the problem.

Here is my new code:

	AttributeReader attrReader; 
	ModelerAPI::Model model;

	Modeler::Sight* sight = nullptr;
	//Modeler::SightPtr currentSightPtr(sight);

	//GSErrCode sightErr = ACAPI_3D_GetCurrentWindowSight((void**)&currentSightPtr);
	GSErrCode sightErr = ACAPI_3D_GetCurrentWindowSight((void**)&sight);
	if (sightErr != NoError) {
		return APIERR_CANCEL;
	}
	Modeler::SightPtr currentSightPtr(sight);
	EXPGetModel(currentSightPtr, &model, &attrReader);

I am testing it.
