dunno, but "try a nightly build, i think there are some jack fixes" does
not necessarily mean "this is a known issue that was fixed only recently"

best would be to try and report (un)success...

>>> "error: JACK error: cannot lock down memory for RT thread (Cannot
>>> allocate memory)"


this error seems to indicate that you are lacking real time priviliges
(what's the content of your /etc/security/limits.d/audio.conf?)

>>> This one appears when I load a complex patch. It also crashes Pd:

you could try to produce a backtrace [1]

>>> Funnily, Pd+Jack works with the same patch - as long as I start Pd
>>> with alsa, and after loading the patch change the audio to jack.

which would indicate that your patch takes too long to load and jack
kicks out Pd....
