c++ - VC++ Access violation reading from private member value types (bool) -

-

i getting weird error access violation reading private class-level values (no pointers).

hresult windowedsinkrenderer::initialize(imlteesink3 *sink) {     std::cout << "test\n";      // exception throw here     std::cout << "test" << _isinitialized << "\n";      std::cout << "test\n";      return s_ok; }

here header

class windowedsinkrenderer { public:     windowedsinkrenderer();     ~windowedsinkrenderer();      hresult initialize(imlteesink3 *sink);     hresult deinitialize();     hresult setrenderowner(hwnd handle);     hresult setrenderdimensions(int width, int height, bool fillvideo);     hresult getcurrentimage(bitmapinfoheader* bitmapheader, byte** data, dword* size, bool* bufferhasinfoheader);  private:      dword _remotegraphregister;     smartptr<igraphbuilder> _graphbuilder;     smartptr<ifiltergraph2> _filtergraph;     smartptr<imediacontrol> _mediacontrol;     windowedvideorenderer* _videorenderer;      bool _isinitialized;  };

and here constructor event initializes bool false.

windowedsinkrenderer::windowedsinkrenderer() : _isinitialized(false) {  }

what gives? why error?

0xc0000005: access violation reading location 0xcdcdcde1.

it looks calling initialize invalid pointer windowedsinkrenderer object.
