It is good that you are sceptical about what I say because it was a
long time ago that I was well oriented in this code.  However, the
problem here is not whether SCM_STRUCT_DATA is operating on the right
type of object.  The real problem is that it is looking after
information which is not stored in an instance.  Furthermore, it is
stored in the class object at a location with a negative offset.
Instances don't have any slots with negative offset.
