            Bug ID: 61732
           Summary: Derivation from final class incorrectly allowed
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: joaquin at tid dot es

I understand that [class]/3 marks this program as ill-formed:

template<class Base> struct derived:Base{};

struct X final{};

void foo(derived<X>*){}

int main()
{
  foo(0);
}

Yet it builds and runs fine in GCC 4.8.
