Summary: Variadic base-specifier-list of union rejected
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: schaub.johan...@googlemail.com
GCC doesn't accept this
template<typename ...T> union A : T... { };
A<> a;
It complains at parse time of "A" about "error: derived union 'A<T>' invalid".
However it doesn't know at that time whether or not the union will have bases
yet when instantiated.
