--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC before 8, is execusively unrolling:
for (j=i; j < npts; j++) {
k[j] = k[j+1]; /* False positive -Warray-bounds issued here */
}
Fixed most likely by r8-5008.

Can confirm the warning no longer appears to issue (at least as of GCC 11).
