to my mind this is the same bug:

https://lists.exim.org/lurker/message/20160311.150529.412cdd3b.en.html

https://bugs.exim.org/show_bug.cgi?id=1807

so, you can apply patch
http://git.exim.org/exim.git/patch/93cc2d6e053031a7008f73ca1ea072038bfa3fc8
and use your original authenticator with ${extract.
