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.
