            Bug ID: 58535
           Summary: [4.8/4.9 Regression] ICE with virtual template
                    function
           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 invalid code snippet triggers an ICE since GCC 4.8.0:

======================================
struct A
{
  template<int> virtual void foo();
};
======================================

bug.cc:3:17: error: templates may not be 'virtual'
   template<int> virtual void foo();

Please submit a full bug report, [etc.]

A c++1y variant crashes (on trunk) without an error message before the ICE:

======================================
struct A
{
  virtual void foo(auto);
};
======================================
