#512: module-jack-sink segfault
---------------------------+------------------------------------------------
Reporter: matth45 | Owner: lennart
Type: defect | Status: new
Priority: high | Milestone:
Component: module-jack-* | Severity: normal
Keywords: segfault |
---------------------------+------------------------------------------------
I am using pulseaudio 0.9.14, the latest release in the Fedora 10 repos,
and jackd 0.116.1.
When I use the module-jack-sink module I frequently get a segfault when
playing audio through the pulseaudio daemon.
I get the following line in dmesg:
{{{
pulseaudio[7224]: segfault at 302d68ef ip 00bc058a sp b271efac error 4 in
libjack.so.0.0.28[bb8000+10000]
}}}
I cannot successfully attach to the running pulseaudio process with gdb -
it slows down too much and breaks the pulseaudio connection to jack. I
also cannot force pulseaudio to leave a core file. I have run ulimit -c
unlimited, and set /etc/security/limits.conf
{{{
* soft core 65536
}}}
and added the following line in daemon.conf:
{{{
rlimit-core = 65536
}}}
Please advise how I can get a core file.
I'm attaching my default.pa and daemon.conf files.
With the attached configuration files, I start jackd as:
{{{
/usr/bin/jackd -v -R -p128 -dalsa -dhw:0 -r48000 -p2048 -n2 -P -S -o2
}}}
I start pulseaudio as:
{{{
pulseaudio --log-level=debug
}}}
I attempt to play a file:
{{{
mplayer -ao pulse /usr/share/sounds/warning.wav
}}}
I have also used the alsa plugin, with the same effect:
{{{
aplay /usr/share/sounds/warning.wav
}}}
I get the following output:
{{{
