This is a stab in the dark, but the patch below corrects this issue for me:
$ ./retest.sh
looking-at: t
re-search-forward: 9
I don't see any reason this should cause regressions (searching
forward 0 steps seems to me it should be the same as searching
backward 0 steps), but I've only casually looked over regex.c.
