Re: Cadaver < lat. cadere?

Etymological dictionaries agree that the widely borrowed Latin
"cadaver" derives from "cadere" 'to fall', but they gloss over the
details.  Where's the -v- from?  I can't tell if this is simply
obvious--if you actually know Latin, which I don't--or genuinely
unknown.
 Many perfect stems have -v-, but cadere has a reduplicating perfect,
cecidi.  Also, the perfect -v- doesn't appear in participle stems,
I think, which would be the most likely source to derive a noun
from.
 So how _is_ cadaver formed from cadere?
 

So far as my resources can take me, nobody seems to know.
The relation with cadere is taken as given in my Lat-Eng dictionary, but OED says "perhaps".
But thank you for an excuse to get out my copy of Walde, Lateinisches Etymologisches Wörterbuch (1906) -- and pay tribute again to my old friend Gloria, who (with me in mind) rescued it from a skip (dumpster) outside the door of her neighbour, a recently deceased scholarly Anglican clergyman.
Yes, well:
cadāver, -eris "Leichnam": wohl P.P.A. "der Gefallene" zu cadābundus, cado (s.d.) (Vaniček 67, vgl. auch Schulze Qu.ep. 250 a 1). Bersus Gutt. 170 abweichende Verbindung mit der in cadamitas (s. calamitas) vorliegenden Wz. von ai. kadanam "Vernichtung" u.s.w. ist unwahrscheinlich, da ein P.P.A.dazu nur "vernichtet habend" bedeuten würde und eine andere Auffassung des Suffixes aussteht.
I thought of one other Latin noun in -āver, namely papāver 'poppy', but it doesn't help much:
papāver, -eris 'Mohn': wohl ptc.pf.act. *papā-ṷes "aufgeblasen, aufgedunsen" (Bildung wie cadāver) zu Wz. *pap- "aufblasen" in pampinus, papula (Vaniček 154).
