[Pkg-octave-devel] Bug#874208: octave: audiodevinfo makes octave segfault when jackd is running

[Peter P.]

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:
