            Bug ID: 58583
           Summary: [c++11] ICE with invalid non-static data member
                    initialization in template
           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 (compiled with "-std=c++0x") is wrongly
accepted since GCC 4.7.0 (when non-static data member initializers were
introduced):

==============================
template<int N> struct A
{
  A* p = new A<N>;
};
==============================

Even instantiating A<0> doesn't produce an error.
However, without template the code is rejected correctly.

A slightly modified code snippet triggers an ICE:

==============================
struct B
{
  template<int N> struct A
  {
    A* p = new A<0>;
  };
};
==============================

bug.cc: In constructor 'constexpr B::A<0>::A()':
bug.cc:3:26: internal compiler error: in tsubst_copy, at cp/pt.c:12810
   template<int N> struct A
