[Bug c++/34962] New: [4.1/4.2/4.3 regression] ICE with VLA and attribute in template

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 4.0.0:

=================================================================
struct A
{
  static const int i;
};

template<int> void foo()
{
  int x[A::i] __attribute((vector_size(8)));
}
=================================================================

bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: tree check: did not expect class 'type',
have 'type' (record_type) in contains_placeholder_p, at tree.c:2267
Please submit a full bug report, [etc.]

This is related to PR34913, but not yet fixed.
