The problem is seen when checking the use_path_follow option (Object Data -> Patch Animation -> Follow).

The problem is in the ob_parcurve function, it needs a par->runtime.curve_cache to run.
But the curve_cache is only seen in the evaluated object. Which is not the case.

I thought of some solutions:

Calculate a temporary cuve_cache in ob_parcurve or;
Pass the evaluated object in BKE_object_get_parent_matrix or;
Create a function that passes the cuve_cache as an optional argument.

But since this is a Copy On Write issue, @Sergey, can you take a look?

@Sergey, using the object->parent evaluated seemed reasonable in this situation. But feel free to try another approach if necessary.
