Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: trippels at gcc dot gnu.org

The testcase from PR65328 shows:
markus@x4 fatal % cat sequence.ii
template <typename T, T... Values> struct A
{
using type = int;
template <type... Suffix> using array = A<type, Values..., Suffix...>;
void
m_fn1 ()
{
array<>::data;
}
};
markus@x4 fatal % g++ -std=c++11 -c sequence.ii
sequence.ii: In member function ‘void A<T, Values>::m_fn1()’:
sequence.ii:8:5: error: incomplete type ‘A<T, Values>::array<> {aka A<int,
Values ...>}’ used in nested name specifier
array<>::data;
^
4.8, 4.9, EDG and clang accept the code.
