--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed.  With trunk and checking enabled:

i.C: In instantiation of ‘void traverse(v4si) [with int C = 0; v4si =
__vector(4) int]’:
i.C:6:31:   required from here
i.C:4:23: internal compiler error: in tsubst_copy, at cp/pt.c:12863
     v4si new_bounds = __builtin_shuffle(bounds,v4si{0,1,2,3});
