freeze on one track

Bug report

Describe the bug

When you have a single song on a looped playlist mpd will sometimes freeze when it finishes. Seems to be happening for a while now, my options are [zxc], nothing's in logs- mpd just locks up with 0 cpu usage and can only be killed with -9, so it's a deadlock i presume. I couldn't catch this on debug build. Switching to next song manually while having one song does not cause the bug.

Log

[MaxKellermann]

Need verbose log and backtrace.

[installgentoo]

i've just caught this with logs on verbose.

there's nothing in log. mpd just freezes.

[MaxKellermann]

If there's nothing in the log file, then either you're looking at the wrong file or MPD isn't playing anything. MPD logs at start and end of playback.
And don't forget the backtrace. I'm unable to analyze your problem without full information.

[MaxKellermann]

Can't help without information.

A year later this is still happening. I just kill and restart mpd through a monitoring script, but the fact that software has freezes isn't good.
Other guy on the internet having this exact same problem: https://www.reddit.com/r/archlinux/comments/9xlqm3/mpd_and_ncmpcpp_freeze_after_last_update/

note that he posted around the same time i encountered the issue.

my config:

`
music_directory "/home/user/music"
playlist_directory "/var/lib/mpd/playlists"
db_file "/var/lib/mpd/database"
state_file "/var/lib/mpd/state"
pid_file "/var/lib/mpd/pid"
user "mpd"
auto_update "yes"
#log_file "/tmp/mpd_log"
#log_level "verbose"

audio_output {
type "alsa"
name "My ALSA Device"
auto_resample "yes"
}

audio_output_format "48000:24:2"

samplerate_converter "soxr high"

volume_normalization "yes"

filesystem_charset "UTF-8"

Can't help without information! I'm serious. If you want to have your problem fixed, you need to post more information.

Debugging hangs is hard.

Debugging hangs is hard.

And you make it impossible by withholding information.

[installgentoo]

well, i mean, verbose log just said the exact same things that it prints on normal song switch and cut off, and i couldn't even catch this in debug build, so i just plugged in a script and forgot about it.

[MaxKellermann]

Let's stop wasting our time by discussing that you're unwilling to post any information. This doesn't lead anywhere.
