Description

1vector < vector<Point> > contours;
2contours.clear(); - ok
3OutputArrayOfArrays &ref = contours;
4ref.clear(); << start

call stack:

     opencv_core249d.dll!cv::_InputArray::type(int i)  Line 1194 + 0xd bytes    C++
     opencv_core249d.dll!cv::_InputArray::type(int i)  Line 1194 + 0xf bytes    C++
     opencv_core249d.dll!cv::_InputArray::type(int i)  Line 1194 + 0xf bytes    C++

>    win32.exe!ContourDetect::getContours(cv::Mat & img)  Line 94 + 0x15 bytes    C++

keep calling:

1int k = kind();

Visual Studio says that:

kind = 0x01381c62 cv::_InputArray::type(int)  ????? how

Could this be related to issue #2218?

I also got a stack overflow related to the kind() function when I compiled with OPENCV_CAN_BREAK_BINARY_COMPATIBILITY, but didn't add that flag to my own program.

Addendum: I've created a new ticket with a better description because the old one was closed: #2358

Variables of types InputArray, OutputArray, InputArrayOfArrays etc. must not be declared explicitly. They are only intended to be used as proxy types for passing parameters to OpenCV functions. Instead, use vector<vector<Point>> or any other type that can be converted to OutputArrayOfArrays.

  • Status changed from Open to Cancelled
