[Bug c++/38579] New: Template: Wrong inherited copy-ctor visibility

[syntheticpp at gmx dot net]

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);
}
