In *scratch*, evaluate:

(funcall
=C2=A0(let ((lexical-binding t))
=C2=A0 =C2=A0(byte-compile
=C2=A0 =C2=A0 (lambda (&optional a b)
=C2=A0 =C2=A0 =C2=A0 (list a b))))
=C2=A0'a 'b)

Result is (a b), as expected.=C2=A0 Now evaluate

(funcall
=C2=A0(let ((lexical-binding t))
=C2=A0 =C2=A0(byte-compile
=C2=A0 =C2=A0 (lambda (&optional a &optional b)
=C2=A0 =C2=A0 =C2=A0 (list a b))))
=C2=A0'a 'b)

Result is (b nil).

Emacs should either generate correct code in both cases, or signal an
error in the latter case.

Fixed with commit =C2=A00d913da15c094bf596dd685acecf34382= 28c15cf.
