2 years ago You're welcome. Unfortunately, I don't know what was on that address. Here's a full gdb log https://pastebin.com/jCS9SFZL
PS. I followed instructions to generate a crash bug report https://mpd.readthedocs.io/en/stable/user.html#crash I looked for a mpd debug package, but I couldn't find any on Fedora 35.
PS2. For a second I thought that this might me somehow related to the mpd client (I tried both ncmpcpp & mpc), but that was a red herring,

A debugging session is active.
Inferior 1 [process 91263] will be killed.
Quit anyway? (y or n) yThis has nothing to do with MPD or a MPD client. This is a crash inside libpipewire, and we still don't know what 0x00007fffc8051590 is, all we know it's not MPD.
Sorry, can't help with a crash inside this third-party library.

2 years ago FYI: The issue went away after updating libpipewire to 0.3.48.
Bug report
Describe the bug
Whenever I stop the playback (via PipeWire) of any track or a stream, mpd crashes.
PS. Switching to pulse audio output fixes the issue. This is a bit strange, because on since Fedora 34, PipeWire runs a PulseAudio compatible replacement server.
Expected Behavior
mpd shouldn't crash when I stop the playback.
Actual Behavior
ditto.
