            Bug ID: 66595
           Summary: [C++14] ICE in partial specialization template
                    variables
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vgheorgh at gmail dot com
  Target Milestone: ---

The code below

template<typename T> int typeID{42};
template<typename T> double typeID<double>{10.10};

int main() {}

produces an internal compiler error 

 > internal compiler error: in type_dependent_expression_p, at cp/pt.c:21431

in both g++5.1 and in HEAD

It should not compile, as the partial specialization doesn't use any of the
template arguments.
