The buffers of cached objects are never modified, but are still stored as a non-constant pointer. This will cause a compiler warning once we enable the `-Wwrite-strings` compiler warning as we assign an empty constant string when initializing the static `empty_tree` cached object. Convert the field to be constant. This requires us to shuffle around the code a bit because we memcpy(3P) into the allocated buffer in `pretend_object_file()`. This is easily fixed though by allocating the buffer into a temporary variable first.
