--- Comment #22 from Martin Sebor <msebor at gcc dot gnu.org> --- Paul, have you considered determining the type of the specialization of the template from an object of one instead of hardcoding its name? I.e., instead of calling gdb.lookup_type("TreeVector<Pod, 2u>::Tree") in your Python printer script, use something like gdb.lookup_type(str(vector.type) % "::Tree")? (I couldn't get this to work but I could have done something wrong.)
