Comment (by joaquin):

 Seems like a bug to me, rather than default behavior. Unfortunately GCC is
 not my area of expertise. Let's do a final try: you can resort to a user-
 defined holder with a slightly different behavior wrt static construction:

 {{{
 template<typename C>
 struct GCC_dyn_holder_class:boost::flyweights::holder_marker
 {
   static C c;
   static C& get()
   {
     return c;
   }
 };

 template<typename C> C GCC_dyn_holder_class<C>::c;

 struct GCC_dyn_holder:boost::flyweights::holder_marker
 {
   template<typename C>
   struct apply
   {
     typedef GCC_dyn_holder_class<C> type;
   };
 };

 typedef boost::flyweight<std::string,GCC_dyn_holder> SymbolName_t;
 }}}

 Does this change anything?
