Bug Related to AcDbMText That Causes AutoCAD Crash

[3453351159]

Following are the key points:

• Add a command CreatText in ObjectARX.

const ACHAR* pContent = L"AA";
void CreateText()
{
	AcDbMText* pText = new AcDbMText();
	AppendDb(pText);
	auto id = pText->objectId();
	pText->close();
	pText = nullptr;
	acdbOpenAcDbEntity((AcDbEntity*&)pText, id, AcDb::kForWrite);
	pText->setContents(pContent);
	pText->close();
	pText = nullptr;
}

Acad::ErrorStatus AppendDb(AcDbEntity* pEntity, const std::wstring& sBlkRec = ACDB_MODEL_SPACE, AcDbDatabase* pDb = acdbCurDwg())
{
	Acad::ErrorStatus es = eNotImplementedYet;

	AcDbBlockTableRecordPointer pBlockTableRecord(sBlkRec.c_str(), pDb, AcDb::kForWrite);
	if ((es = pBlockTableRecord.openStatus()) != Acad::eOk)
		return es;

	return pBlockTableRecord->appendAcDbEntity(pEntity);
}

• Execute the command.
• Undo .
• Attempt to close the drawing, choose not to save, then AutoCAD crashes.

This issue occurs both in AutoCAD 2018 and 2022.

Very strange code:

pText->setContents(pText);

I'm sorry, I posted a error code.It has been fixed now. However, this doesn't affect the test results.
