The accessors of original ID and objects are expected to return nullptr for the nullptr input. This was handled explicitly in the DEG_get_evaluated_id(), but the DEG_get_evaluated_object was using `object->id` without check. While it did not cause actual issue (as the id's offset is 0), this was causing address sanitizer error print. Pull Request: https://projects.blender.org/blender/blender/pulls/108939
