Summary: double free bug
Initial Comment:
I run on localhost icecast and liquidsoap. Configuration for liquidsoap is
really simple:
#!/usr/bin/liquidsoap -v
set log.dir = "/tmp"
set log.stdout = true
output =
output.icecast(mount="test.ogg",host="localhost",port=8000,password="source")
output =
output.icecast.mp3(mount="test.mp3",host="localhost",port=8000,password="source")
output(playlist.safe("playlist.pls"))
playlist.pls contains 15 files, 2 of them are not available.
Running liguidsoap on the liquidsoap instance and clicking several times on
"on/off" on the playlist controller crashes liquidsoap:

What else can I provide to solve this?

I couldn't reproduce this bug. I'm using:
* glibc 2.3.6
* libshout 2.2.2
* ocaml-shout and liquidsoap from SVN.
I also took care of exporting MALLOC_CHECK_=1 in order to make sure that
my glibc reports such errors. Then I launched a simple .liq script with an
icecast.mp3 output, connected to it via liGuidsoap and clicked on/off like
crazy for several seconds. Everything went fine for me.
I had a similar bug report by mail, a long time ago. The conclusion was
that sometimes, when a shout connection attempt failed, a double free
occured somewhere and the glibc consequently sent SIGABORT to liquidsoap.
I don't think it is related to your playlist but only to a too fast
re-connection to shout.
I'm not 100% sure that ocaml-shout is OK, but I wouldn't exclude libshout
itself here.
I'll mark the issue closed for now. It's really not severe, and should be
worked around by exporting MALLOC_CHECK_=0.
However, if you want to try harder on that bug please precise the version
of glibc, libshout, ocaml-shout and liquidsoap (the two latter are SVN if
I understood well), try on a simple output.icecast.mp3(blank()), check
with the output.icecast() too, and check the env variable MALLOC_CHECK_.
Finally, setting MALLOC_CHECK_=2 should crash the program better, allowing
you to get a backtrace in gdb.

What version of liquidsoap did you use? Could you try with a version built
from a fresh SVN checkout?
Also, a gdb stacktrace would help us a lot.
