Did not work for me, shows as a regular JPEG, although I fiddled with
it a bit... looks like it's meant to target this code, right?

      s += state.last_dc_val[ci];
      state.last_dc_val[ci] = s;
      /* Scale and output the coefficient (assumes jpeg_natural_order[0]=0) */
      (*block)[0] = (JCOEF) (s << Al);

The bug is pretty subtle, took me a while to figure it out. Kudos.
