        CPoint cpt;
        ::GetCursorPos(&cpt);
        Acad::ErrorStatus status;
        AcDbDatabase *pNewDb=NULL;
        AcDbDatabase *pDbBack = new AcDbDatabase(Adesk::kFalse);;
        status = pDbBack->readDwgFile(filepath);

    status = pDbBack->wblock(pNewDb);

        AcGePoint3d ptTemp = pDbBack->extmin();
        AcGePoint3d ptCurrent(cpt.x,cpt.y,0.0);
        AcGeVector3d vecTemp(ptCurrent.x-ptTemp.x, ptCurrent.y-ptTemp.y ,ptCurrent.z-ptTemp.z);

       
        AcGeMatrix3d matrTemp;
        matrTemp.setToTranslation(vecTemp);
        //matrTemp.setToScaling(0.01);
        delete pDbBack;
        status = acdbHostApplicationServices()->workingDatabase()->insert(matrTemp, pNewDb);
        if (pNewDb)
        {
                delete pNewDb;
                pNewDb = NULL;
        }

上面的代码是将一个dwg文件中的模型层实体添加当前的数据库中，并增加位移。


报出溢出的错误。

求解各位大虾分析，跟踪半天了。
