The following invalid testcase triggers an ICE since GCC 4.4.0
(when the meaning of the auto keyword changed).

==========================
template<int> struct A
{
  int a[auto(1)];
};
==========================

bug.cc:3:16: internal compiler error: in fold_convert_loc, at fold-const.c:2671
Please submit a full bug report, [etc.]

A similar code snippet is wrongly accepted:

==========================
template<int> void foo()
{
  int a[auto(1)];
}
==========================

It is rejected when foo is instantiated, but (given the first example)
this is probably too late.

------- Comment #1 from paolo dot carlini at oracle dot com  2010-05-04 16:32 -------
Apparently now *both* snippets are wrongly accepted, at least in mainline.
