Details:

$ find -noop
[1]    4043 segmentation fault (core dumped)  find -noop

This is a result of the parse table entry having a NULL function pointer here:
http://git.savannah.gnu.org/cgit/findutils.git/tree/find/parser.c?id=9cb4175a172f47a6fcd3b20bd65f7a3c1c0637ec#n326

I'm not sure why that entry has to be part of parse_table itself.  get_noop()
looks for it but I think

static const struct parser_table noop = {ARG_NOOP, "noop",                 
NULL, pred_true };

static const struct parser_table*
get_noop (void)
{
  return &noop;
}

would probably work fine.
