[Bug c++/35026] New: [4.3 regression] ICE with parameter pack in pointer type

[reichelt at gcc dot gnu dot org]

The following invalid code snippet is accepted on mainline:

=====================================
template<typename... T> struct A
{
  T* x[1];
};

A<int> a;
=====================================

One can also trigger ICEs with the snippet if one compiles it with "-g":

bug.cc: In instantiation of 'A<int>':
bug.cc:6:   instantiated from here
bug.cc:2: internal compiler error: in gen_type_die_with_usage, at
dwarf2out.c:13432
Please submit a full bug report, [etc.]

or with "-gstabs":

bug.cc: In instantiation of 'A<int>':
bug.cc:6:   instantiated from here
bug.cc:2: internal compiler error: in dbxout_type, at dbxout.c:2237
Please submit a full bug report, [etc.]
