How can one get a backtrace of PD if for example, you get a segfault? I was thinking of gdb, but not sure exactly what to do, as I don't know whether PD runs in several threads, etc.
The problem is using PD with Jack, and using the -audiodev command and entering more than one audio device, eg 1,2. With 1 only, PD stays running, but with more than 1, it segfaults shortly after startup.
Turns out this is proper behavior. With Jack, there is no real number of audio devices. Using the -inchannels and -outchannels arguments got what I wanted.

:) Well, not sure if segmentationfaults can be called proper behaviour, anyhow, you are right, the JACK implementation should not accept the -audiodev flags and should not segfault.
