how to deal with this assertion debug failure-CodePudding

I am debugging a code that generates five dxf files. Everything works correctly for the first generation. As soon as I start creating the second dxf file I get this error.

Could someone help me and explain me the problem. I am not able to post the whole code because the code is very big. thanks in advance

The reason for this failure was that I used these two data types in the wrong way: 1- const wchar_t* 2- wstring

class KDXFDWGWRAPPERTEIG_API K_ArcParameter {
   private:
      struct K_2DPoint { double m_point_1; double m_point_2; };

      K_Teigha3DPoint m_arcCenter{ 0.0, 0.0, 0.0 };
      K_Teigha3DPoint m_arcNormal{ 1.0, 1.0, 0.0 };
      K_2DPoint     m_arcAngleParameter{ 0.0, 3.14 };
      K_DxfDwgColor m_defColor;
      double            m_radius = 1.0;
      double            m_thickness = 0.5;
      const wchar_t*         m_layerName = L""; // error is here
      const wchar_t*            m_lineType = L"";// error is here
   public:
// C-Tor
K_ArcParameter(K_Teigha3DPoint pArcCenter, K_Teigha3DPoint pArcNormal, K_2DPoint pArcAngleParameter, double pRadius) :
    m_arcCenter(pArcCenter), m_arcNormal(pArcNormal), m_arcAngleParameter(pArcAngleParameter), m_radius(pRadius), m_defColor(0x000000ff) {};
K_ArcParameter(K_Teigha3DPoint pArcCenter, K_Teigha3DPoint pArcNormal,K_2DPoint pArcAngleParameter, double pRadius, double pThickness, wstring& pLayerName, wstring& pLineType) :
    m_arcCenter(pArcCenter), m_arcNormal(pArcNormal), m_arcAngleParameter(pArcAngleParameter), m_radius(pRadius), m_thickness(pThickness), m_layerName(pLayerName), m_lineType(pLineType), m_defColor(0x000000ff) {};
K_ArcParameter(K_Teigha3DPoint pArcCenter, K_Teigha3DPoint pArcNormal, K_2DPoint pArcAngleParameter, K_DxfDwgColor pDefColor, double pRadius, double pThickness, wstring& pLayerName, wstring& pLineType) :
    m_arcCenter(pArcCenter), m_arcNormal(pArcNormal), m_arcAngleParameter(pArcAngleParameter), m_defColor(pDefColor), m_radius(pRadius), m_thickness(pThickness), m_layerName(pLayerName), m_lineType(pLineType) {};

//methods
K_Teigha3DPoint         getArcCenterPoint()     const { return m_arcCenter; }
K_Teigha3DPoint         getArcNormal()      const { return m_arcNormal; }
K_2DPoint               getArcAngleParameter()      const { return m_arcAngleParameter; }
K_DxfDwgColor           getColor()      const { return m_defColor; }
double                  getRadius()     const { return m_radius; }
double                  getThickness()      const { return m_thickness; }
wstring                 getLayerName()      const { return m_layerName; }
wstring                 getLineTypeName()       const { return m_lineType; }
bool                    IsLineTypeByLayer()     const { return false; }


 };

The layer name and linetype name must be wstring. The const wchar_t* is not allowed and crashes my debugger. I'm sorry I didn't post the code as it's very extensive and I wasn't able to see the specific error location. I hope this can help you guys.
