It's an uninitialized variable.

In worktree.c:delete_blob() we have

        err = get_file_status(&status, &sb, ie, ondisk_path, -1, NULL, repo);
        if (err)
                goto done;

        if (S_ISLNK(sb.st_mode) && status != GOT_STATUS_NO_CHANGE) {
                char ondisk_target[PATH_MAX];
                ssize_t ondisk_len = readlink(ondisk_path, ondisk_target,
                    sizeof(ondisk_target));

However, if the open() in get_file_status() fails with ENOENT, then
there is no *stat() call and sb is never set.  On my FreeBSD machine,
this leads to S_ISLNK(sb.st_mode) spuriously triggering the readlink()
branch.
