No. I'm using a C-like approach and only pointers in the bison token union. 

I use an external string hash which keeps track of all allocated strings 
and makes sure that each identifier is actually only allocated once during 
parsing and all subsequent occurances are merely referenced. 

And there is an external list which keeps track of all those tree nodes which 
get dropped during error recovery.
