The following code compiled in g++ 3.3.4, but does not compile in the latest
4.0.x
Seems like a regression testing oversight.
template <typename T, typename ID_TYPE=long>
class db_reference {
private:
T r;
public:
ID_TYPE &id;
db_reference(ID_TYPE req_id=0);
T &get();
std::string print(int full_subtables=0, int show_ids=1, int no_refs=0)
const;
std::string print_xml(int full_subtables=1, int show_ids=0, int no_refs=1,
const char *tag=0) const;
void parse_xml(std::string &buf, const char *tag);
void parse(const std::string &buf);
void parse(const SQL_ROW &buf);
operator T() const;
T *operator ->();
const T *operator ->() const;
db_reference<T,ID_TYPE> &operator =(T &t);
db_reference<T,ID_TYPE> &operator =(const db_reference<T,ID_TYPE> &t);
};
template <typename T, typename ID_TYPE>
db_reference<T,ID_TYPE>::db_reference<T,ID_TYPE>(ID_TYPE req_id) : id(*(ID_TYPE
*)(&(r.id))) {
id=req_id;
}
The error is
error: invalid use of constructor as a template
note: use db_reference<T, ID_TYPE>::db_reference instead of db_reference<T,
ID_TYPE>::db_reference<T, ID_TYPE> to name the constructor in a qualified name
