Hi again, and, to be very very precise, I even renamed my directory now [which appears in the compilation trace] because its previous name was terrible (and terribly wrong)! so, the appropriate directory name is: .../setter-inheritance-bug
[ the new trace is here below, 'in place'
[ the rest of the text is unchanged
[ and I still pretend it is a bug
Cheers,
David
