[Bug c++/34271] New: [4.3 regression] ICE in invalid initialization of static template member

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

=====================================================
template<int> struct A
{
  static int i;
};

template<int N> int A<N>::i(__decltype( A::i ));
=====================================================

bug.cc:6: internal compiler error: in finish_decltype_type, at
cp/semantics.c:4158
Please submit a full bug report, [etc.]


A slightly modified testcase crashes in a different position:

=====================================================
template<int> struct A
{
  static int i;
};

template<int N> int A<N>::i(__decltype( A::i;
=====================================================

bug.cc:6: internal compiler error: in lvalue_p_1, at cp/tree.c:149
Please submit a full bug report, [etc.]
