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.
