it's a known error in your friend's code <grin>.  heap corrupted means that 
the heap free list got confused somehow... this can happen any number of ways, 
of which my favorite is free()ing the same piece of memory twice... or better 
yet, free()ing (or disposing) a variable that wasn't dynamically allocated in 
the first place..
