Ugh, this is bizarre. When I enter in a dest_node like so
var dest_node = ll_pfind_getClosestNode(my, entTarget.x, 1000, NULL);
it gives me that error. It doesn't seem to like my pointer or something... Because if I use player.x it works fine.
(the pointer is defined exactly the same way it is in your scripts, I've checked.)
EDIT: I got it, finally. When defined as void instead of action, pathfinders can find the object pointed to.

Technically it shouldn't matter if you're using void or action. However, the last time I checked your script, the movement code could invoke random behaviour, as the you pointer (which was not set) and a var instead of a VECTOR were used. Make sure you ar using something like this:
VECTOR vec_to_target;
vec_diff(&vec_to_target, &node->pos, &my->x);
vec_to_angle(&my->pan, &vec_to_target);
c_move(my, vector(10 * time_step, 0, 0), nullvector, GLIDE);

I'm at my wit's end here... It was working; then it stopped.
action test_pather()
{
path_set(my, "path_000");
var start_node = ll_pfind_getClosestNode(my, my.x, 1000, NULL);
var dest_node = ll_pfind_getClosestNode(my, player.x, 1000, NULL);
LL_LIST *path = ll_pfind_getPathToTarget(my, start_node, dest_node, ll_pfind_astarCost);
while(!path)
{
beep();
wait(1);
}
}
This beeps, which shouldn't be happening. If I use the full script, I get errors when trying to modify the list; and I get a bit_array error when I compile the full script.
