In the above, make sure the header for std::pair is included -
impossible to see from your example. Perhaps the class used as a
pointer needs to be instantiated before - try it without the 'union'.
Sometimes "using namespace std" may cause problems - try without it.
And you do not mention which Bison version you are using - in case it
is a know bug fixed. Just some inputs.
