Thread: Xtree - '_Debug_Message' ?

I'm a student just learning C++ after a couple years of working with Java, so I'm an intermediate programmer, I'd say. I'm doing some homework in which I need to create a child class of the data container 'set', and I'm using Microsoft Visual C++ Studio 2005 to do it. I was doing fine until right up at the end, I made a small change in how an iterator was being incremented in the Union method and then my program would no longer compiled. I undid the change, and tried to recompile but I got the same error. Upon looking closer at the error message I see it doesn't even relate to my source, but "xtree" which I can only assume is the internal symbol linker(?) Can someone help me walk through correcting the error? I'd greatly appreciate the help, and can post the source on request. Here's the error message in it's entirety, and my source file is MySet.cpp:

1) The Windows board is for programming problems that are specific to the Win32 API, or one of its wrappers. Please post questions such as these in the general C++ board. If they are about compiler configuration, please post them in tech.

2) You have homework that asks you to derive from std::set?
