I suspect that you're a victim of the ol' switcheroo.  You 
should catch the return from the createEnd because the old
reference to allAgents is probably gone.

This may not be the problem, though.  You might want to use
the debugger and find out exactly which object (or whatever)
was supposed to be there when you accessed that memory.
