Debug Assertion failed in OpenCV HoughCircles Example (C++) from xstring in VS2013

Question

I am using Visual Studio 2013 on Windows 8.1, with OpenCV installed. I have copied the example hoghCircles() code and have built it, but I get an error in "line 1168" of xstring.

Any help would be appreciated :)

Since you haven't really provided much detail I am hazarding a guess here.

Are you running the debug version from within the debugger? If so you need to go to the property pages of the project and add a command argument so it has an image to work with.
