            Bug ID: 59096
           Summary: [4.9 Regression] [c++11] ICE with template attribute
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following valid code snippet (compiled with "-std=c++11") triggers an ICE
on trunk:

====================================
template<typename T> struct A
{
  typedef T B [[mode]];
};

A<int>::B b;
====================================

bug.cc: In instantiation of 'struct A<int>':
bug.cc:6:7:   required from here
bug.cc:3:22: internal compiler error: Segmentation fault
   typedef T B [[mode]];
