[Bug c++/32567] New: [4.3 regression] ICE on invalid use of parameter pack

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

============================================================
template <typename... T> struct A
{
  static T &t;
  static const int i = sizeof(++t);
};

int x[A<int>::i];
============================================================

bug.cc:3: error: parameter packs not expanded with `...':
bug.cc:3: note:         'T'
bug.cc: In instantiation of 'const int A<int>::i':
bug.cc:7:   instantiated from here
bug.cc:4: error: invalid use of template type parameter 'T'
bug.cc:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in get_unwidened, at tree.c:5887
Please submit a full bug report, [etc.]
