Bug#727307: segfaults after 3 days

[Antoine Beaupré <anarcat@debian.org>]

Package: liquidsoap
Version: 1.0.1+repack1-1.1
Severity: normal

quidsoap[16658]: segfault at fffffffffffffffb ip 00007f4c35df4a59 sp 00007f4c2addd560 error 5 in libc-2.13.so[7f4c35d79000+180000]

This happened after 3 days of continuously running, at the end of a
song, the stream just disappeared.

I couldn't find teh core dump, since liquidsoap seems to run with a CWD
of /, I assume it couldn't be written. I have attached a gdb process to
it to catch it when it crashes next time.

Here's a copy of my configuration:

#!/usr/bin/liquidsoap

# anarcat radio liquidsoap file.

# log to the logdir
# disabled while we test
set("log.file.path","/var/log/liquidsoap/anaradio.log")

# Listening icecast server settings
set("harbor.bind_addr","0.0.0.0")

# Store passwords in another configuration file,
# so that the main config can be safely version-controlled.
%include "passwords.liq.inc"

# checklist:
# 1. favorite playlist
# 2. random playlist
# 3. jingles playlist
# 4. manual playlist
#
# if 4, play it
# else play a weighted mix of 1,2,3

# 1. favorite playlist
favorites = playlist.safe(reload_mode="watch", '/srv/playlists/Favoris.m3u')

# 2. random playlist
shuffle = playlist('/srv/mp3')

# 2.1 incoming random playlist
incoming = playlist('/srv/incoming')

# play incoming one out of 15 times
shuffle = rotate(weights = [1, 15], [incoming, shuffle])

# 3. jingles playlist
jingles = playlist.safe(reload_mode="watch", '/srv/playlists/jingles.m3u')

# 3.1 strangelove
jingles = rotate(weights = [1, 10], [playlist('/srv/playlists/strangelove.m3u'), jingles])

# play favorites roughly half the time, and jingles every 15 songs
radio = rotate(weights = [5, 10, 1], [favorites, shuffle, jingles])

# 4. manual / live input
# XXX: this introduces significant latency and overhead, would need to
# be replaced by an RTP multicast listener
live = input.harbor("radio.ogg",port=8001,password=pass)

# time-configurable crossfade
def crossfade(t,a,b)
  add(normalize=false,
	  [ sequence([ blank(duration=t/2.),
	               fade.initial(duration=t,b) ]),
	    fade.final(duration=t,a) ])
end

# output live if available, fallback on radio
# we crossfade between the two, we could add jingles when switching, see also
# http://liquidsoap.fm/doc-svn/cookbook.html
output.icecast(%vorbis,
  host = "localhost", port = 8000,
  url = "http://anarc.at/services/radio";,
  description = "Anarcat Radio!",
  password = pass, mount = "radio.ogg",
  fallback(track_sensitive=false,
           transitions=[crossfade(5.),crossfade(3.)],
           [live,radio]))

# XXX: missing RTP multicast output
