The autogenerated operator= would take non-const ref if any of the data 
members' operator= required that.  The only suspiciously-looking one in 
TokenInfo is StringHashMap aProperties, which is a boost::unordered_map. 
 Something wrong with the boost version maybe (assuming that the 
problem happens --with-system-boost)?
