 From Sean Huang, on the Boost mailing list:

 The following code in function_template.hpp has me concerned:

     template<typename Functor>
     void assign_to(Functor f)
     {
       static vtable_type stored_vtable(f);
       if (stored_vtable.assign_to(f, functor)) vtable = &stored_vtable;
       else vtable = 0;
     }

 The function scope statics are not thread-safe as far as I know and this
 is
 potentially a show stopper for us (we're in the process of upgrading from
 1.33.1 to 1.34+. Same usage in boost.serialization caused our application
 (very heavy threaded) to crash.
