better?
somewhat, but not much.
apart from that:
- what's the output of 'ulimit -a'
- is there a difference if you start jackd with/without realtime settings?
- is there a difference if you start jackd with/without memory locking?
- does it crash if you start Pd without jackd running?
- why don't you get the "Cannot lock down XXX byte memory area
(Operation not permitted)" error (on the console) that i get?
- what's the output of Pd (on the terminal and/or console) if you use a
different backend: './pd -verbose -rt -alsa'
IOhannes, thanks for your patience.
dpkg -S /usr/lib/x86_64-linux-gnu/libjack.so.0 | sed -e 's|:.*|-dbgsym|'
gives
libjack-jackd2-0-dbgsym
Following https://wiki.ubuntu.com/Debug%20Symbol%20Packages the variable $(lsb_release -cs) gives me "sonya" on Mint 18.2, had to change this manually to xenial..... Thinking of not installing Mint the next time or going for something like LMDE, debian or arch... anyway, that's OT. However, I have the KXStudio repositories installed, so the standard Ubuntu debug symbols don't help me, because they are for a different version. I should try downgrading jack, maybe that already solves the issue.

no, still segfaults
- what's the output of Pd (on the terminal and/or console) if you use a

Then switching to jack output in Pd for the fun:
Segmentation fault

- does it crash if you start Pd without jackd running?
no:

how?
