The code below compiles, but it should give an error, because the Policy ctor
is not accessible when inheriting protected from Policy
To have valid C++ code the inheritance must be public.
struct Policy
{
protected:
Policy() {}
Policy(const Policy&) {}
};
template<int I, class P>
struct BugGcc :
protected P
//public P
{
BugGcc() {}
template<int I, class P>
BugGcc(const BugGcc<I, P>& t) : P(t) {}
};
void foo()
{
BugGcc<0, Policy> f1;
BugGcc<1, Policy> f2(f1);
}
