Package: octave
Version: 4.2.1-2
Severity: normal
Dear Maintainer,
audiodevinfo makes octave segfault when jackd is running. I don't know
if the octave audio functions are supposed to support jack. If they
don't it would be great if octave could nevertheless survive. Thank you
for looking into this, I am happy to help where I can.
Here is the gdb backtrace:

Closing this bug now, since no new information has been added for
almost three years.
Peter: if you are still affected by this bug with a recent version of
Octave, feel free to reopen.
