The following (IMHO valid) code snippet triggers an ICE on mainline:
==================================================
int x[5];
template<int M, int N, int (&... p)[N]> struct A;
template<int M> struct A<M,5,x> {};
A<0,5,x> a;
==================================================
bug.cc:7: internal compiler error: tree check: accessed elt 2 of tree_vec with
1 elts in tsubst, at cp/pt.c:8528
Please submit a full bug report, [etc.]
