No, they should not.  `ind', however, needs to be initialized.  Try
instead adding

        ind = r - ret;

before the call to RESIZE_MALLOCED_BUFFER and see if that fixes it.

        p++;
  
+       ind = r - ret;
        RESIZE_MALLOCED_BUFFER (ret, ind, 2, rlen, rlen);
        r = ret + ind;                  /* in case reallocated */
