I doubt it is a bug in weak_ptr, weak_ptr::lock() is pretty much the  
same code as copying a shared_ptr. (see constructors of shared_count).

have you tried valgrind? afaik there is an experimental port for mac  
os. if shared_ptr/weak_ptr delete an object that is still in use  
valgrind should catch that.
