Re: c++ actions

[Hans Aberg]

Your info is so sparse, leaving it to the imagination of everybody else as
well. Perhaps you try to use %union together with a type with nontrivial
constructors and a compiler that does not check that it is illegal C++.
Perhaps you try to compile the C parser as C++, together with a type with
nontrivial assignment. Or there might be something wrong with your own code.
