Hi

Even this code did not help.However I finally fixed it.
I replaced "REsult" with my own var like this :-

Code:

---

vec_set(temp,my.x);
	temp[2] -= 4000;
	dist = c_trace(my.x,temp,IGNORE_ME|IGNORE_MODELS|IGNORE_SPRITES|IGNORE_PASSENTS);
	if (dist < 10) {
		my.z -= (dist - 1);
		vec_to_angle(temp,normal.x);
		my.tilt = temp[1];
		my.pan = temp[0];
	}
	

---

I think this error looks like machine specific,which is scary !
Thanks so much for the help.
