JIT/VM calls incorrect method about hashlink HOT 3 CLOSED

i've been playing around with the code and i got things working, but i am not a hundred percent sure i am not breaking anything. my changes are in safe cast, to me it looks like the issue is that since my other class contains a member that is first in the fields array it breaks and return false without checking if the expected fields are included.

this seems to work fine in what little tesiting i've done

case HVIRTUAL:
		if( to->virt->nfields < t->virt->nfields ) {
			int i, j;
			int matches = 0;
			for(i=0;i<to->virt->nfields;i++) {
				hl_obj_field *f2 = to->virt->fields + i;
				for(j=i; j < t->virt->nfields;j++) {
					hl_obj_field *f1 = t->virt->fields + j;
					if( f1->hashed_name == f2->hashed_name && hl_same_type(f1->t,f2->t) ) {
						matches++;
						break;
					}
				}
			}
			if( matches == to->virt->nfields )
				return true;
		}
		break;
		````

just adding this for some more context, to maybe help find a different root causeof my problem.
if i add this to hl_safe_cast

if (t->kind == HOBJ && to->kind == HVIRTUAL) {
		vdynamic * d =  *(vdynamic**)t->obj->global_value;
		vvirtual* conv = hl_to_virtual(to, d);
		return hl_safe_cast(conv->t, to);
	}

(must of course be before this line to have any effect)

if( t->kind != to->kind )
		return false;

the typedef example also runs just fine, but it feels more like the issue is related to hl_to_virtual and what effect null values for fields ( hl_vfields(v)[i] = NULL; ) has to the later execution.

before i modified the HVIRTUAL case in hl_safe_cast hl_to_virtual would set the field to NULL and this some how made the code try to execute a different method, maybe some kind of index missmatch between the real object type and the interface.

without the code above, the typdef seems to get the same problem, hl_vfields(v)[i] = NULL, and later on it throws an Access Violatio error.
