[Crash report] Pipewire causes Ardour 6 to segfault, when it would not have crashed with Jack

I built Ardour 6.6.185 (synced to fe99dd4ec2cfa6be7b70bf4479caab49ed5e3014), and I tried using it with both Jack and Pipewire pretending to be Jack. With Jack, I was able to load up projects and edit tracks. I did have some slight problems with Jack itself like in general but no crashes. With Pipewire, however, loading any project with Pipewire's fake Jack causes the application to segfault. Ardour 5 does work fine though, which is interesting. I tried various ways of building Ardour 6 and all of them resulted in the same segfault.

Output of uname -a

Linux zyth 5.8.0-48-generic #54~20.04.1-Ubuntu SMP Sat Mar 20 13:40:25 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

I have attached a diagnostic copy of the results of bash alsa-info_alsa-info.sh

Basically my steps were:

  1. Compile fftw-3.3.9 
    export CFLAGS="-fPIC"
./configure --enable-threads --with-pic --enable-fma --enable-float --enable-sse
make
sudo make install
  2. Compile ardour (extra arguments were me trying to avoid this segfault; still didn't avoid it though). 
    ./waf --use-external-libs --libjack=weak --use-lld configure
./waf --use-external-libs --libjack=weak --use-lld
  3. Run ardour 
    cd gtk2_ardour
./ardbg
  4. kill pulseaudio
  5. Running the installed pipewire and pipewire-media-session with pulseaudio still live works too to produce this crash.
  6. Load an existing project and connect to Jack.
  7. The project will try to load then segfault.

Edit: figured out how to provide trace due to your documentation. Thanks!
