No idea why in commit 01ecb7172b684f1c4b3e748f95c5a9a494ca36ec the
checks were removed; this can lead to NULL pointer dereferences. This
effectively reverts that portion of the commit.

Big shame that len-1 is -1 mod 4; 0 mod 4 would have yielded a further 2x

additional symmetry. Of course, one could approximate with the 0 mod 4 variant,
error would essentially be ~ 1/len in the worst case.
