Hi. The below is accepted by GCC and rejected by ICC. It's consistently
rejected if I remove any trace of namespace detail:
namespace detail
{
template<typename A, typename B>
class one;
template<typename C>
class one<int, C>;
}
template<typename T>
class two
{
template<typename A/*, typename B*/>
friend class detail::one;
int num;
};
namespace detail
{
template<typename C>
struct one<int, C>
{
void f()
{
two<int> t;
t.num = 1;
}
};
}
int main()
{
detail::one<int, double> o;
o.f();
}
