If you look at line 570 in database.ixx, just above it you will see
this comment:

// Compiler error pointing here? Perhaps the object doesn't have the
// default constructor?
//

So your problem is the fact that class Inspection doesn't have the
default constructor. Object without default constructors cannot be
used in relationships.

Seeing that you have a circular relationship, you may also find
Section 6.3, "Circular Relationships" in the ODB manual relevant.
