Hey all,
I'm running OpenCV 2.4.11 on Windows 7, compiling with Visual Studio 2015.
I've found that during several function calls (to `Stitcher::Stich` and `cv::findContours`, for example), there is a critical memory error that causes the program to crash consistently.
For these errors, I get an error like the following in visual studio:
Debug Assertion Failed!
Program: ...a\code\my-project\software\Debug\my-project.exe
File: C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\xmemory0
Line: 116
Expression: "reinterpret_cast(_Ptr_ptr)[-1] == _BIG_ALLOCATION_SENTINEL" && 0
When I follow the call stack to find out where the crash happened, it always happens at the end of a function when local variables go out of scope. The error is usually on the line:
my-project.exe!std::_Deallocate>(cv::Point_ * _Ptr, unsigned __int64 _Count) Line 114 C++
or similar (I believe when I call `Sticher::stitch` the crash is for a vector of type `cv::DMatch` rather than `cv::Point`).
If I comment out the specific lines (such as `cv::findContours`), the program runs just fine. In fact, the program works just fine until `cv::findContours` actually finds a contour; in this case it immediately crashes with the above memory errors.
I've checked that I have the right `.dll` files, and I do -- I'm wondering if perhaps I need to rebuild OpenCV for Visual Studio 2015? I'm not sure what else would be causing this problem.
thanks!
