--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed. Looks like this has started very recently (sometime in the last
week). But a VRP dump from GCC 7 shows the same range:
_9 = i.0_1 + 4294967286;
_10 = arr[_9];
...
Found new range for _9: [4294967286, +INF]
...
_9: [4294967286, +INF]
