apt-cache policy ardour

  Installed: 1:5.12.0-3
  Candidate: 1:5.12.0-3

What I expected:  Use of plugin for compression.

What I got:  Segfault in calf.so

ardour-5.12.0[2204]: segfault at 26d0c1360 ip 00007f797dc9c850 sp
00007fff57485b30 error 6 in calf.so[7f797dbea000+109000]

This is a fresh install of Ubuntu 18.10 in a VM, with ubuntustudio-audio
installed.

Upon inspection, there are two versions of calf.so installed:

chick@dd:~$ ls -l /usr/lib/ladspa/calf.so
-rw-r--r-- 1 root root 1179344 Mar  9  2018 /usr/lib/ladspa/calf.so
chick@dd:~$ ls -l /usr/lib/calf/calf.so
-rw-r--r-- 1 root root 2354968 Jul 30  2017 /usr/lib/calf/calf.so
chick@dd:~$ 

Removing the /usr/lib/ladspa/calf.so and replacing with a link to
/usr/lib/calf/calf.so solves the problem.
