pulseaudio-0.9.16(test2 and test3) crashed on some actions

Description

Hello, I have another crash report. After I upgrade to 0.9.16, pulseaudio and libcanberra works very well most time, but when I actively chatting (in gajim, sound events via paplay) and at the same time switching to other window (i.e. libcanberra sends event), pulseaudio sometimes crashed and restarted. And for some time I can't do anything becuase of full gtk freeze. So, I have gdb report of crash

Which distro is this? Is this Fedora Rawhide?

It's gentoo amd64

BTW, I think that freezing gtk on pulse crash is a bad idea.

Looks like brokeness in glibc's iconv. The abort() was triggered there. Please redo the bt with debug symbols installed.

Changed 3 years ago by lennart

full debug symbols that is, of glibc and pa.

I found that iconv maybe because of log-level = info, so I commented it and restarted pulseaudio. After some time (and my actions) it crashed again with these messages in console: I recompile pulse with CFLAGS="-ggdb" and glibc with debug. I think that gdb is additional factor and can affect result, so I analyze coredump, not running program. Result is attached.

Sorry, old version :) delete "with these messages in console:"

pulseaudio just crashed with another error

And another crash, now with message: E: memblock.c: Assertion 'segment->n_blocks >= 1' failed at pulsecore/memblock.c:522, function memblock_free(). Aborting.

Last one (gdb-pulse5.log) was also with these messages:

Hmm, this is weird. You seem to be hitting quite a few assert()s here, all over the place. Which is a bit surprising since on Fedora Rawhide we have about *zero* of those.

Do you think you are able to run PA through valgrind? This should give us a few hints what might be going wrong.

Which PA version is this exactly?

Changed 3 years ago by Yaroslav

I use pulseaudio-0.9.16-test3 (pulseaudio-0.9.16_rc3.ebuild from portage) on Linux 2.6.30, glibs is 2.9_p20081201-r2 (git snapshot, stable package).

How can I run PulseAudio through valgrind? I install it and what to do now?

Changed 3 years ago by Yaroslav

Hmm, I restart pulseaudio with valgrind --log-file=log --leak-check=full --leak-resolution=med --trace-children=yes pulseaudio It's ve-ery slow and crackling, but works. Because of some strange conditions, I can't reach a crushed state, but valgrind is very verbose. After I restart pulseaudio and try to actively chatting, pulseaudio crashes again with:

So, I attach valgrind's log

BTW. Please, can you make CWD of pulseauido equal to $HOME? Because if it is run as a non-root user, CWD is still "/" and pulseaudio can't make a coredump (because I don't have rights to write to "/")

I believe this has been fixed in a more recent PA snapshot from git. Could you verify? If you can reproduce this, please reopen and append valgrind output of a build with full debug symbols.

Instead of fiddling with CWD for coredumps it is probably a batter idea to use /proc/sys/kernel/core_pattern and to redirect the dumps into a fixed syste directory.

BTW: it's not recommended to use gdbm anymore as database. Use tdb instead.

That valgrind output is very enlighting. It would be better still if I could convince you to redo it with debug symbols enabled?
