audio/jack: jackd coredumps on HEAD

[Rainer Hurling]

My system: HEAD amd64 r276612, pulseaudio-5.0_2.
Audio system: Surround Sound 5.1.

When I try to start jackd in an environment with a working pulseaudio,
jackd coredumps (please see output from within gdb). This also happens
without setting output to 6 channels (-o 6).

Does anyone else see this error?

Any help is really appreciated. Thanks in advance and let me know, if I
should provide more info.

Regards,
Rainer Hurling
