Is this (1) a new bug [possibly a CS bug], (2) an old bug, or (3) a

(%i1) declare(a,nonscalar);
(%o1)                                        done
(%i2) featurep(a,nonscalar);
(%o2)                                       false
(%i3) trace(featurep);
(%o3)                                     [featurep]
(%i4) featurep(a,nonscalar);
1 Enter FEATUREP [a, nonscalar]
1 Exit  FEATUREP false
(%o4)                                       false
