Hi Vincent, I have no time for perusing the code, but searching the net shows that the value "FEEEFEEE" is "Used by Microsoft's C++ compiler to mark the storage area of a deleted class in debug mode". IOW, some object is being used after its deletion. Try to find places where ref_ptr should be used.
More memory codes at http://en.wikipedia.org/wiki/Magic_debug_values#Magic_debug_values. It is also easier to debug step by step through the program and see in what line the crash is produced.
