Thanks. Latest CVS version of GCCXML dumps artificial declarations. It
is the only way to reliably find-out whether a class has public
destructor or not.

For example, next use case is not covered by the posted code:

struct XXX{

private:

virtual ~XXX(){}

};



struct YYY : public XXX{

};



/*void do_smth(){

    YYY y;

}

*/


SVN version of pygccxml was updated.

I suggest you to switch to the latest versions

P.S. If nothing wrong happens, I will start working on next release - 1.0
