Okay, the segfault in jack_capture has been fixed. I
had screwed up the handling of jack shutdown. New

I think though, that the reason jack shut down in the
first place, is because of a bug in jack. I don't know
the status of that situation. Perhaps someone on the
jack list can say something about whether it has
been fixed.
Hello Kjetil!
I just installed and ran jack_capture a couple of times. Sometimes it
crashes with this:
jack_capture[28116]: segfault at 08072000 eip 0804b1f0 esp bffa6c70 error
6
Segmentation fault
Funny, now I tried it again, it doesn't do it again. The error message was
something like:
...
zombified
JACK shutdown.
The setup was: LinuxSampler running and MPlayer playing. Recording from
mplayer or recording from LinuxSampler with MPlayer finished.
The zombified error only came, when I hit RETURN ctrl-c respectively. So
it didn't crash while working there.
Any idea why that might have happend? Oh one last note: I don't have
meterbridge installed.
Kindest regards
Julien
Ouch, thanks for reporting. But I'm not quite sure what happened.
Is this the correct events?:
1. Started LinuxSampler and Mplayer
2. Started jack_capture without any arguments.
3. Pressed RETURN or ctrl-c in jack_capture terminal
4. Got the message "zombified" and "JACK shutdown"
in jack_capture terminal
5. jack_capture segfaults
Also, which version of jack are you running? There was
a bug in jack recently which could make jack crash when a program
exited. (I don't think jack_capture shouldn't segfault even because
of that bug though)
