It looks like from line 2272 or so in the current sources of eval.c:

      if (XSUBR (fun)->max_args == UNEVALLED)
        {
          backtrace.evalargs = 0;
          val = (*XSUBR (fun)->function) (args_left);
          goto done;
        }

I looked closely. We got it.


"UNEVALLED" indicate that the evaluation of a function must mut evaluate its arguments.

Thanks a lot.
