There are
/* This should give the number of parameters. */
total_args = list_length (new_args);
arg_array = XNEWVEC (tree, total_args);
ii_args = new_args;
for (ii = 0; ii < total_args; ii++)
{
arg_array[ii] = TREE_VALUE (ii_args);
ii_args = TREE_CHAIN (ii_args);
}
TREE_USED (function) = 1;
rest_of_decl_compilation (function, 0, 0);
call1 = cilk_call_setjmp (cfun->cilk_frame_decl);
if (*arg_array == NULL_TREE)
call2 = build_call_expr (function, 0);
else
call2 = build_call_expr_loc_array (EXPR_LOCATION (*spawn_p), function,
total_args, arg_array);
When total_args == 0, XNEWVEC (tree, total_args) doesn't return
NULL and "*arg_array" will be wrong.
