Currently we are using pointers. The whole point of glr2.cc (vs. glr.cc) is precisely to allow genuine C++ objects to be semantic values. Let's make that work. * data/skeletons/glr2.cc (glr_state::glr_state): Be sure to initialize yysval. (glr_state): Add copy-ctor, assignment and dtor. (glr_state::copyFrom): Be sure to initialize the destination if it was not. (glr_state::~glr_state): Destroy the semantic value. * examples/c++/glr/ast.hh: Rewrite so that we use genuine objects, rather than a traditional OOP hierarchy that requires to deal with pointers. With help from Bruno Belanyi <bruno.belanyi@epita.fr>. * examples/c++/glr/c++-types.yy: Remove memory management. Use true objects. (main): Don't reach yydebug directly. * examples/c++/glr/local.mk: We need C++11.
