Description

Error can be reproduced with following code.

int _tmain(int argc, _TCHAR* argv[]) {
Mat image;
Mat scaledImage;

image.create(1000,1000,CV_8UC3);
  resize(image, scaledImage, Size(), 0.33, 0.33, INTER_CUBIC);
  scaledImage.release();
return 0;
}

Upon returning from resize(), scaledImage is correct. When deallocate() is called from within release() it causes an access violation. It seems to have something to do with scaledImage being allocated by resize(), but I can't sort it out.

If I allocate scaledImage and call resize with scaledImage.size() and fx=fy=0, then scaledImage.release() works fine.

I am using Visual C++ Express 2010 on Windows 7. Compiling as 32 bit code.

The problem can not be reproduced on my machine. Make sure you link debug version of opencv to debug version of your application and release version of opencv to release version of your application.
